Explication 〜以内 in your Level:

At the A1 level, learners are just beginning to navigate the Japanese language, focusing on basic survival phrases and fundamental vocabulary. While this specific term might seem slightly advanced for absolute beginners, its practical utility makes it essential early on. A1 learners will primarily encounter it in the context of simple time and money. For instance, when shopping, understanding that a price is within a certain budget is crucial. Similarly, when asking for directions, hearing that a station is within a five-minute walk provides immediate, actionable information. The grammatical structure at this stage is kept very simple: just a number, a counter, and the term itself. Learners do not need to worry about complex abstract applications yet. Instead, the focus is on rote memorization of common phrases like 'within ten minutes' or 'within one thousand yen'. This helps build confidence in daily interactions. Teachers often introduce this concept alongside basic numbers and time expressions, reinforcing the idea of limits. Through repetitive practice, A1 students learn to associate the sound of the word with the concept of a boundary. Visual aids, such as clocks or maps, are highly effective in demonstrating this. By mastering these basic applications, learners lay a solid foundation for more complex usages in the future. It is also important for A1 learners to understand that this term includes the number mentioned, a subtle but critical point that prevents misunderstandings. Although their vocabulary is limited, incorporating this word allows beginners to express constraints and understand simple rules, significantly enhancing their communicative competence in everyday situations. As they progress, the contexts in which they use this word will naturally expand, but the core concept of a defined limit remains unchanged. Therefore, early exposure and practice are highly beneficial for long-term retention and mastery. The emphasis is on comprehension and basic production in highly predictable, everyday scenarios.

As learners progress to the A2 level, their ability to handle everyday situations expands significantly, and so does their use of this boundary-setting term. At this stage, students are learning to manage schedules, make plans, and understand more detailed instructions. Consequently, the word becomes a vital tool for discussing deadlines and timeframes. A2 learners will frequently use it to say things like 'I will return within an hour' or 'Please submit the homework within three days'. The grammatical integration becomes slightly more complex, as learners must now consistently use the particle 'ni' to indicate the deadline for an action. This requires a deeper understanding of sentence structure than the simple noun phrases used at the A1 level. Furthermore, A2 students begin to encounter the word in written contexts, such as short emails, notices, and simple signs. They learn to recognize the kanji characters, which reinforces their reading comprehension. The concept of spatial limits also becomes more relevant, as learners describe distances between locations with greater accuracy. For example, they might explain that their house is within a two-kilometer radius of the school. Teachers at this level often create role-play scenarios that require students to negotiate times and set limits, providing practical application for the vocabulary. It is also at this stage that the distinction between inclusive and exclusive limits (like 'miman') is explicitly taught, ensuring that learners do not make critical errors when following rules or instructions. By the end of the A2 level, students should feel comfortable using this word to manage their daily lives in Japanese, expressing constraints and understanding the expectations set by others with a reasonable degree of accuracy and confidence. The focus shifts from mere survival to active participation in routine exchanges.

Reaching the B1 level marks a significant milestone in a learner's journey, characterized by increased independence and the ability to handle a wider range of topics. At this intermediate stage, the focus word becomes an indispensable part of the student's active vocabulary, particularly in professional and formal contexts. B1 learners are expected to understand and produce clear, detailed texts, and this term is crucial for articulating conditions, rules, and strict deadlines. In business Japanese, which is often introduced at this level, the word is used constantly in emails, proposals, and meeting agendas to establish clear expectations. For example, a B1 student should be able to confidently write, 'Please reply within this week' or 'Keep the presentation within fifteen minutes'. The grammatical usage also expands to include modifying other nouns using the particle 'no', such as 'delivery within three days' (mikka inai no haitatsu). This allows for more sophisticated and concise sentence structures. Furthermore, learners begin to apply the concept to abstract limits, such as 'within the scope of the budget' or 'within common sense'. This demonstrates a deeper cognitive grasp of the word's versatility beyond mere physical or temporal boundaries. Listening comprehension at this level involves catching this term in natural, moderately paced speech, such as announcements at train stations or instructions from a supervisor. Teachers challenge B1 students to use the word in debates or discussions where setting parameters is necessary. The ability to distinguish it accurately from similar terms like 'ika' and 'miman' is now expected, as precision becomes increasingly important. Mastery of this word at the B1 level signifies that the learner can navigate the rules and boundaries of Japanese society with competence, making their communication more effective, polite, and culturally appropriate. It is a key indicator of intermediate fluency.

At the B2 level, learners are approaching an advanced degree of fluency, capable of understanding complex texts and expressing themselves spontaneously and fluently. The use of this boundary term at this stage reflects a high level of nuance and precision. B2 students encounter the word in authentic, unsimplified materials, such as news articles, editorials, and literature. Here, it is often used in discussions of legal frameworks, economic policies, or statistical data. For instance, a news report might state that 'inflation was kept within two percent' or 'the suspect was apprehended within the city limits'. Learners must be able to instantly comprehend these usages without hesitation. In their own production, B2 students use the word to construct complex arguments and articulate precise conditions. They might use it in academic essays to define the scope of their research or in professional presentations to outline project constraints. The grammatical application is flawless, with correct particle usage and appropriate register. Furthermore, learners at this level understand the subtle psychological implications of the word—how it can be used to create a sense of urgency, reassure a client, or establish a firm, non-negotiable boundary. They can seamlessly integrate it into complex sentence structures, combining it with conditional clauses or passive voice. Teachers at the B2 level focus on refining the learner's ability to choose the absolute best word for a specific context, ensuring that the distinction between this term and its synonyms is completely internalized. The word is no longer just a vocabulary item to be translated; it is a conceptual tool used to navigate and describe complex systems and rules. Mastery at this level means the learner can use the term as naturally and effectively as a native speaker in a wide variety of demanding communicative situations.

The C1 level represents an advanced, near-native proficiency where learners can express ideas fluently and spontaneously without much obvious searching for expressions. At this stage, the focus word is deeply embedded in the learner's linguistic repertoire, used with complete accuracy and sophisticated nuance. C1 learners encounter and utilize this term in highly specialized and technical contexts, such as legal contracts, academic research papers, and complex corporate negotiations. In these environments, the precise definition of boundaries is paramount, and any misunderstanding can have significant consequences. A C1 user can effortlessly draft a contract clause stating that 'claims must be filed within thirty days of the incident' or analyze a scientific paper discussing variables 'within a specific margin of error'. Their understanding of the word extends to idiomatic and highly formal usages. They are also acutely aware of the sociolinguistic aspects of the word, knowing exactly when its use is appropriate to assert authority or establish a formal tone. In spoken Japanese, they can use it effectively in high-stakes environments, such as defending a thesis or leading a business strategy meeting, where clear communication of limits and expectations is crucial. The grammatical execution is automatic, and the learner can play with sentence structures to emphasize the boundary being set. At this level, teachers rarely need to correct the usage of this specific word; instead, discussions might revolve around the stylistic choices of using this term versus a more complex, specialized alternative. The C1 learner's mastery of this word demonstrates their ability to handle the rigorous demands of professional and academic Japanese, showcasing a deep, intuitive understanding of how boundaries are linguistically constructed and maintained in Japanese society.

At the C2 level, the highest level of proficiency, the learner's command of the language is virtually indistinguishable from that of a highly educated native speaker. The use of this boundary term is entirely instinctive, fluid, and perfectly adapted to any conceivable context. C2 users can comprehend the word in the most obscure or complex literary texts, historical documents, or highly abstract philosophical discussions. They appreciate the subtle stylistic and rhetorical effects the word can achieve. For instance, they might analyze how an author uses the concept of 'within' to create a sense of claustrophobia or strict societal constraint in a novel. In their own expression, C2 learners use the word with absolute precision, often employing it in sophisticated metaphorical or poetic ways that go far beyond its literal meaning of time or space. They can debate the legal or ethical implications of boundaries defined by this word with native-level eloquence and cultural sensitivity. Their vocabulary is so vast that they can effortlessly substitute this term with highly specific synonyms depending on the exact shade of meaning required by the context. The word is fully integrated into their complex web of linguistic knowledge, connecting seamlessly with advanced grammar patterns, nuanced particles, and varied registers. At this pinnacle of language learning, the focus is not on the mechanics of the word, but on its power as a tool for sophisticated thought and expression. The C2 learner wields this term not just to communicate limits, but to shape arguments, define realities, and interact with the Japanese language at its deepest, most profound level. Their mastery is absolute, reflecting a comprehensive internalization of Japanese linguistic and cultural paradigms.

〜以内 en 30 secondes

Indicates a strict limit.
Includes the stated number.
Used for time, space, and money.
Essential for setting deadlines.

The Japanese suffix and noun inai is an absolutely essential component of everyday communication, business transactions, and formal writing. It fundamentally denotes the concept of being within a specific limit, boundary, or threshold. This boundary can be temporal, spatial, numerical, or even abstract. When you append this term to a number, a counter, or a specific time frame, you are establishing a strict parameter that cannot be exceeded. For example, if a teacher tells a student to submit an assignment within three days, the use of this term makes it unequivocally clear that the fourth day is unacceptable. This precision is highly valued in Japanese culture, where clarity and adherence to rules are paramount for maintaining social harmony and operational efficiency.

三日〜以内に提出してください。

As you can see in the example, the boundary is set clearly. Beyond just time, it applies to physical distances. If a sign says that a parking lot is within fifty meters, it provides a reliable expectation for the driver.

Spatial Limit: Indicates that a location or object is located at a distance no greater than the specified amount.

This spatial application is incredibly common in real estate listings, navigation apps, and giving directions. Furthermore, it is heavily used in financial contexts. A budget might be restricted to being within ten thousand yen.

一万円〜以内で買い物をします。

This ensures financial discipline. The versatility of this word means you will encounter it constantly.

Financial Limit: Used to cap expenses, budgets, or pricing to a maximum allowable amount.

It is also vital for understanding legal and official documents, where conditions are often bound by strict limits.

一週間〜以内に返事が必要です。

If you fail to grasp the inclusive nature of this limit, you might miss deadlines or violate terms. The psychological impact of using this word is also interesting; it creates a sense of urgency and clarity.

五分〜以内に戻ります。

When someone says they will return within five minutes, it is a firm commitment.

Temporal Limit: Defines a maximum duration or a strict deadline for an action to be completed.

Finally, let us look at abstract limits, such as being within the scope of the law or within reason.

常識の範囲〜以内で行動する。

This shows that the concept of a boundary is not just physical or numerical, but also conceptual. Mastering this word allows you to navigate all these boundaries effectively, making your Japanese much more precise and natural. It is a cornerstone of B1 level proficiency and beyond. To truly internalize this concept, you must practice applying it across these diverse scenarios. Consider how a boundary changes the meaning of a sentence. Without it, a statement might be a vague suggestion; with it, it becomes a definitive rule. This transformation is why the word is so frequently used in professional settings. In business, ambiguity is the enemy of productivity. Therefore, setting clear parameters using this terminology ensures that all parties share the same expectations. Whether it is a delivery window, a project milestone, or a budget constraint, the explicit nature of this word eliminates confusion. Furthermore, understanding its nuances helps you interpret the expectations placed upon you by others. When a supervisor asks for a report within a certain timeframe, recognizing the strictness of that boundary allows you to prioritize your tasks accordingly. This level of comprehension goes beyond mere vocabulary acquisition; it is about cultural fluency and professional competence. As you continue to study, pay close attention to the contexts in which native speakers employ this term. Notice the subtle differences in tone and urgency. By doing so, you will not only expand your vocabulary but also deepen your understanding of Japanese communication styles. This holistic approach to language learning is what ultimately leads to true mastery. So, embrace the boundaries, understand the limits, and use this powerful word to communicate with confidence and clarity in any situation.

Understanding how to correctly implement this term in a sentence is vital for clear communication. The grammatical structure is remarkably consistent, making it relatively easy to master once you grasp the basic pattern. Primarily, it attaches directly to a quantifier, which includes a number and a counter. This combination forms a noun phrase that acts as an adverbial modifier in the sentence, dictating the limits of the action or state described. For instance, when dealing with time, you simply place the word immediately after the time duration.

一時間〜以内に終わらせる。

This straightforward structure is the backbone of its usage.

Direct Attachment: The term directly follows the number and counter without any intervening particles.

It is crucial to remember that no particle is needed between the counter and the limit word. However, when it modifies another noun, the particle 'no' is required.

三日〜以内の返却。

This transforms the phrase into an adjective-like modifier for the following noun.

Noun Modification: Use the particle 'no' when the limit phrase directly modifies a subsequent noun.

This pattern is frequently seen in official documents and formal instructions. Another common usage involves the particle 'ni', which indicates the time by which an action must be completed.

今週〜以内に支払う。

The 'ni' particle here functions similarly to 'by' or 'within' in English, setting a firm deadline. When discussing scope or range, the word can also be used with nouns that imply a boundary, such as 'han-i' (scope).

予算の範囲〜以内で。

In this case, the particle 'no' connects the noun to the limit word.

Scope and Range: Used with nouns denoting range or scope to emphasize staying within those boundaries.

Finally, it can be used in negative constructions to emphasize that something should not exceed the limit.

十名〜以内に抑える。

This means keeping the number to ten or fewer. Mastering these various grammatical connections will allow you to use the word fluidly and accurately in any context. The key is consistent practice and paying attention to the particles that accompany it. By internalizing these rules, you will avoid common grammatical errors and sound much more natural. Remember that the absence or presence of a single particle can significantly alter the meaning or grammatical correctness of your sentence. Therefore, meticulous attention to detail is required. As you practice, try creating your own sentences using different counters and nouns. This active engagement with the grammar will solidify your understanding and improve your overall proficiency. Furthermore, reading authentic Japanese texts will expose you to the myriad ways this word is employed by native speakers. You will notice its prevalence in news articles, business correspondence, and even casual conversations. This exposure is invaluable for developing an intuitive sense of how the word functions within the broader ecosystem of the Japanese language. Continue to challenge yourself by incorporating it into increasingly complex sentence structures. Over time, what once required conscious effort will become an automatic and seamless part of your linguistic repertoire. The journey to fluency is paved with such incremental victories, and mastering this essential term is a significant step forward.

The ubiquity of this term in Japanese daily life cannot be overstated. You will encounter it in an incredibly wide array of contexts, ranging from the mundane to the highly formal. One of the most common places you will hear or see it is in transportation hubs. Train stations, airports, and bus terminals rely heavily on precise timing and clear spatial directions.

駅から徒歩五分〜以内。

Real estate advertisements frequently use this phrasing to highlight the convenience of a property's location.

Real Estate: Used to describe the proximity of a property to essential services or transportation.

In the realm of retail and commerce, it is equally prevalent. When you make a purchase online, the delivery estimate will almost certainly employ this word. Similarly, return policies dictate the timeframe within which a product can be sent back.

三十日〜以内なら返品可能です。

This sets a clear, unambiguous boundary for the consumer.

Customer Service: Establishes the rules and time limits for returns, exchanges, and warranties.

Moving into the corporate world, the term is a staple of business communication. Deadlines for reports, project milestones, and meeting durations are all defined using this vocabulary.

明日の午前中〜以内に提出。

In a culture that prizes punctuality and reliability, adhering to these stated limits is crucial for professional success. Furthermore, you will encounter it in medical settings. Prescriptions often come with instructions on how quickly medication should be consumed after a meal.

食後三十分〜以内に服用。

Here, the limit is a matter of health and safety.

Medical Instructions: Provides precise timing for taking medication or following health guidelines.

Finally, it appears frequently in academic environments. Exam instructions specify the time limit for completing the test.

六十分〜以内に解答すること。

In all these diverse scenarios, the core function of the word remains the same: to establish a clear, non-negotiable boundary. Recognizing its widespread use will help you appreciate its importance and motivate you to master its application. Whether you are navigating a new city, making a purchase, working in a Japanese office, or taking a test, your ability to understand and respond to these limits will significantly impact your experience. It is not just a word; it is a fundamental tool for organizing and regulating life in Japan. By familiarizing yourself with these common contexts, you will be better prepared to comprehend the information presented to you and to communicate your own needs and constraints effectively. This practical knowledge is what bridges the gap between classroom learning and real-world fluency. So, keep your ears and eyes open. You will be surprised at how often this essential term appears once you start looking for it. Every encounter is a chance to reinforce your understanding and build your confidence in using the Japanese language.

Even advanced learners can stumble when using this term, primarily due to subtle nuances and interference from their native language. One of the most frequent errors is confusing it with terms that mean 'less than'. In English, 'within 10 days' and 'less than 10 days' might sometimes be used interchangeably in casual conversation, but in Japanese, the distinction is rigid.

十日〜以内 (Includes the 10th day).

If you use a word meaning 'less than', the 10th day is strictly excluded.

Inclusivity Error: Failing to recognize that the stated number is included in the acceptable range.

This mistake can lead to missed deadlines or incorrect quantities. Another common pitfall involves grammatical particles. Learners often incorrectly insert the particle 'no' between the counter and the limit word.

Incorrect: 三日の〜以内

The correct form is to attach it directly.

Particle Insertion: Unnecessarily adding 'no' between the number/counter and the suffix.

This makes the sentence sound unnatural to native speakers. Conversely, learners sometimes forget the particle 'ni' when specifying a deadline for an action.

Correct: 明日〜以内に連絡する。

Without 'ni', the sentence lacks the necessary grammatical connection to the verb. A third area of confusion is using this term for physical locations when another word would be more appropriate. While it works for distances (within 5 km), it is not typically used to mean 'inside a building'.

Incorrect: 部屋の〜以内にいる。

In this case, 'naka' (inside) is the correct choice.

Contextual Misuse: Using the term for physical containment rather than a numerical or spatial limit.

Finally, learners sometimes struggle with the pronunciation, particularly the vowel length.

Pronunciation: いない (i-na-i)

Ensuring each mora is pronounced clearly is essential for being understood. By being aware of these common mistakes, you can proactively avoid them and refine your Japanese. It is natural to make errors during the learning process, but understanding the root cause of these specific pitfalls will accelerate your progress. Pay close attention to the examples provided in your textbooks and by native speakers, noting exactly how the word interacts with surrounding vocabulary and grammar. Practice writing sentences that specifically target these problem areas, such as contrasting inclusive and exclusive limits, or using the correct particles. Over time, these distinctions will become intuitive, and your communication will become much more precise and effective. Remember, mastering a language is not just about learning new words; it is about understanding their boundaries and how they fit into the larger puzzle of grammar and context. Stay vigilant, keep practicing, and you will overcome these common hurdles with ease.

Navigating the landscape of Japanese vocabulary requires a keen understanding of synonyms and related terms. While our focus word is incredibly useful, it exists alongside several other terms that express similar, yet distinct, concepts. Understanding these subtle differences is a hallmark of advanced proficiency. One of the most closely related terms is 'ika' (以下), which translates to 'less than or equal to'.

千円以下 (1000 yen or less).

Like our focus word, 'ika' is inclusive of the stated number.

Ika (以下): Means 'below or equal to'. Often used for scores, ages, or prices.

However, 'ika' is more commonly used for vertical scales or hierarchies, whereas our focus word is preferred for time and distance boundaries. Another crucial term to distinguish is 'miman' (未満), meaning 'less than'.

十八歳未満 (Under 18 years old).

The critical difference here is that 'miman' is exclusive; it does not include the stated number.

Miman (未満): Strictly 'less than'. The specified number is excluded from the acceptable range.

Confusing these two can lead to significant legal or practical issues, such as underage drinking or missing a strict cutoff. When discussing time, learners also encounter 'aida ni' (間に), meaning 'while' or 'during'.

夏休みの間に (During the summer vacation).

While both relate to timeframes, 'aida ni' emphasizes an action occurring at some point during a continuous period, whereas our focus word emphasizes the strict deadline at the end of that period.

Aida ni (間に): Focuses on the duration or the span of time in which an event happens.

Furthermore, 'uchi ni' (うちに) is another temporal expression meaning 'while' or 'before a state changes'.

明るいうちに (While it is still light).

This carries a nuance of urgency before an opportunity is lost, distinct from the objective boundary set by our focus word.

期限〜以内 (Within the deadline).

By carefully studying these comparisons, you can select the most precise vocabulary for your intended meaning. This level of precision is what elevates your Japanese from merely functional to highly articulate and nuanced. Do not just memorize translations; understand the specific conditions and implications of each word. Practice substituting them in sentences to see how the meaning shifts. This analytical approach to vocabulary building will serve you well as you encounter increasingly complex texts and conversations. The richness of the Japanese language lies in these subtle distinctions, and mastering them is a rewarding and essential part of your learning journey. Keep exploring these connections, and your vocabulary will become a powerful tool for exact expression.

Comment l'utiliser

nuance

Implies a hard limit. Not a flexible suggestion.

formality

Appropriate for all levels of formality.

written vs spoken

Equally common in both.

regional variations

Standard Japanese, understood nationwide without variation.

Erreurs courantes

Adding 'no' between the counter and 以内 (e.g., 3日の以内).
Thinking it excludes the stated number (confusing it with 未満).
Forgetting the particle 'ni' when setting a deadline for a verb.
Using it for physical containment (like 'inside a box') instead of 中.
Confusing it with 以外 (igai - except) due to similar pronunciation.

Astuces

Direct Attachment

Always attach 以内 directly to the counter. Never use 'no' between the number and the word. Memorize '10分以内' as a single unit.

Inclusive Nature

Remember that the number is included. 5日以内 means you have until the end of the 5th day. Don't confuse it with exclusive terms.

Ni vs De

Use 'ni' for deadlines (actions completed by a time). Use 'de' for budgets or limits (actions done using an amount).

Contrast with Miman

Learn 以内 alongside 未満 (miman). Knowing that miman excludes the number helps solidify that inai includes it.

Clear Vowels

Pronounce every mora clearly: i-na-i. Don't rush it or slur it into 'inay'. Clear pronunciation ensures you are understood.

Email Deadlines

Use this word in business emails to set clear expectations. '明日以内に' is much clearer than just '明日'.

Look for the Kanji

Familiarize yourself with the kanji 以内. You will see it on signs, tickets, and forms constantly in Japan.

Spatial Limits

Practice using it for distances. '駅から徒歩5分以内' is a standard phrase you should be able to say and understand instantly.

Noun Modification

When writing, remember to add 'no' if a noun follows. '3日以内の返事' (a reply within 3 days).

Respect the Limit

Understand that in Japan, a limit is a limit. If it says 'within 10 minutes', aim for 8. Punctuality is key.

Mémorise-le

Moyen mnémotechnique

Imagine an 'E' (い) 'Nigh' (ない) - The deadline is E-nigh (very near), so finish it WITHIN the time!

Origine du mot

Sino-Japanese (On'yomi)

Contexte culturel

Creates a firm boundary. Using it implies a strict rule rather than a soft suggestion.

Extremely high. Essential for contracts, emails, and scheduling.

Neutral/Formal. Can be used in any polite or casual context.

Questions fréquentes

10 questions

Yes, absolutely. This is a crucial point. If you say '3日以内' (within 3 days), it means the action can happen on day 1, day 2, or day 3. The third day is fully included in the acceptable timeframe. This is different from '未満' (miman), which excludes the number.

No, you do not. You attach 以内 directly to the counter. For example, '10分以内' (10 minutes within) is correct. Saying '10分の以内' is grammatically incorrect and sounds unnatural to native speakers. Treat the number, counter, and 以内 as a single block.

Use '以内に' (inai ni) when you are setting a deadline for an action to be completed, like 'submit within 3 days'. Use '以内で' (inai de) when you are setting a limit or boundary within which an action occurs or a state is maintained, like 'buy it within 1000 yen' or 'finish it within 10 minutes' (focusing on the limit of the resource).

Yes, but usually in terms of distance, not being 'inside' a room. For example, '駅から1キロ以内' (within 1 km from the station) is perfectly natural. However, to say 'within the room', you should use '部屋の中' (heya no naka), not '部屋の以内'.

Both include the stated number. However, '以内' is primarily used for boundaries of time, distance, and specific limits (within a range). '以下' (ika) is used for quantities, scores, ages, or levels on a vertical scale (less than or equal to). You use '1000円以内' for a budget limit, but '60点以下' for a failing score.

To use a phrase with 以内 to describe another noun, you must use the particle 'の' (no). For example, '10分以内の距離' (a distance of within 10 minutes). The 'no' connects the limit phrase to the noun it describes.

Yes, it is very common in casual conversation. While it is essential for formal business, friends use it all the time. For example, '5分以内に行くね' (I'll be there within 5 minutes). It is a versatile word that doesn't sound overly stiff in daily life.

Yes, you can use it with abstract boundaries, often combined with words like '範囲' (han'i - scope). For example, '常識の範囲以内で' (within the bounds of common sense). This shows that the limit isn't just numerical but conceptual.

In Japanese culture, deadlines set with '以内' are considered strict. Missing them, especially in business or academic settings, is seen as a breach of trust. It is always better to finish well before the limit rather than pushing right up to it.

No, '以内' is consistently inclusive in standard Japanese. If a sign says '50km以内', 50km is the absolute maximum allowed. There are no common exceptions where it means strictly 'less than'.
