〜付き

The Japanese suffix 〜付き (tsuki) is an incredibly versatile and essential component of the Japanese language, particularly at the B1 intermediate level. Derived from the continuative form (ren'youkei) of the verb tsuku (付く), which means 'to be attached' or 'to adhere to,' this suffix functions to indicate that a primary object or service comes equipped with, includes, or is accompanied by something else. In the landscape of daily Japanese life, you will encounter this word everywhere—from the bustling corridors of Tokyo's train stations to the quiet menus of rural ryokans. It serves as a linguistic shorthand to describe bundled features, inclusive services, and physical attachments. When you see a noun followed by 付き, it fundamentally changes the status of that noun from a standalone item to a 'package deal.' This concept is deeply rooted in the Japanese service culture (omotenashi), where the inclusion of extras is often expected and clearly labeled to ensure customer satisfaction and clarity in transactions.

Core Meaning

With; including; furnished with; attached to; containing as a feature.

In practical terms, 〜付き is the 'plus' factor. Imagine you are booking a hotel room. A simple 'room' is just heya. However, a room that includes breakfast becomes choushoku-tsuki (朝食付き). This distinction is vital for both the consumer and the provider. It moves beyond mere possession (which might use the verb motteiru) and describes an inherent or bundled characteristic of the subject. The beauty of this suffix lies in its efficiency; it eliminates the need for complex relative clauses or multiple sentences to describe what is included. It is particularly prevalent in commercial contexts, such as real estate listings, restaurant menus, and product specifications, where clarity regarding 'what you get for your money' is paramount. Furthermore, it extends into abstract realms, such as 'conditions' (jouken-tsuki) or 'guarantees' (hoshou-tsuki), demonstrating its flexibility across various domains of Japanese communication.

Understanding the nuance of 〜付き also requires recognizing its social weight. In Japan, where precision and politeness are intertwined, specifying exactly what is included in a deal prevents misunderstandings and reflects a high level of professional etiquette. For example, a job offer that is koutsuuhi-tsuki (transportation expenses included) is much more appealing and clear than one that vaguely mentions benefits. Similarly, in social settings, being described as un-tsuki (lucky/with luck) suggests that luck is an inherent quality currently attached to the person. This suffix essentially glues two concepts together—the base noun and the 'extra'—creating a unified concept that is greater than the sum of its parts. As you progress in your Japanese studies, mastering 〜付き will allow you to navigate commercial transactions with confidence and describe the world around you with the same specificity that native speakers do.

Common Usage Scenario 1

Hospitality: Describing hotel plans (e.g., with meals, with hot spring access).

Common Usage Scenario 2

Real Estate: Listing apartment features (e.g., with air conditioning, with parking).

Finally, it is worth noting the grammatical transformation that occurs. While tsuku is a verb, tsuki functions as a noun-like suffix. This means it can be used to end a sentence (e.g., ...tsuki desu) or to modify other nouns. This dual nature is what makes it so prevalent in signage and advertising. It acts as a label. When you walk through a Japanese electronics store like Yodobashi Camera, you will see hoshou-tsuki (with warranty) plastered on various products. This isn't just a description; it's a selling point. By learning this suffix, you aren't just learning a word; you're learning how Japanese society categorizes and markets value. Whether it's a physical attachment like a 'strap-attached' phone case or an abstract 'condition-attached' agreement, 〜付き is the linguistic glue that holds these complex ideas together in a simple, readable format.

Mastering the sentence structures involving 〜付き (tsuki) is a gateway to sounding more natural and precise in Japanese. The most basic and common structure is [Noun A] + [Noun B] + 付き. In this construction, Noun A is the 'extra' or the 'feature' that is attached to Noun B. However, in many contexts, Noun B is implied, and the phrase simply becomes [Noun A] + 付き to describe the state of the subject. For example, in a restaurant, raisu-tsuki (ライス付き) means 'comes with rice.' The subject (the meal) is understood from the context. This suffix essentially functions as a post-positional modifier that creates a new compound noun. Understanding how to integrate this into various sentence patterns is crucial for B1 learners who are moving beyond simple 'Subject-Object-Verb' structures into more descriptive and nuanced language.

Pattern 1: Noun + 付き (Standalone/Predicate)

[Subject] は [Feature] 付き です。 (The subject comes with [feature].)

Pattern 2: Noun + 付き + の + Noun

[Feature] 付き の [Object] (An object that comes with [feature].)

Let's look at the first pattern. When you say Kono pasokon wa mause-tsuki desu (このパソコンはマウス付きです), you are stating that 'This computer comes with a mouse.' Here, mause-tsuki acts as the predicate. This is very common in sales, customer service, and descriptive writing. It provides a clear, definitive statement about the attributes of an item. The second pattern, using the particle no, is used when you want to use the entire 'feature-included' concept to describe another noun. For instance, kamera-tsuki no keitai (カメラ付きの携帯) means 'a mobile phone with a camera.' Without the no, the sentence would be grammatically incomplete if you intended to modify the phone. This distinction is a common stumbling block for learners, but once grasped, it allows for the creation of complex and descriptive noun phrases that are essential for higher-level communication.

Another important aspect of using 〜付き is its role in compound words that have become standardized in Japanese. Words like teishoku (set meal) often imply certain inclusions, but when a specific addition is made, 〜付き is used to clarify. For example, dezāto-tsuki (with dessert). In more formal or technical settings, 〜付き can be used to describe conditions or attachments in a more abstract sense. Jouken-tsuki (conditional/with conditions) is a prime example. You might hear jouken-tsuki no shounin (conditional approval) in a business meeting. This demonstrates that the suffix isn't limited to physical objects but is a conceptual tool for indicating 'attachment' in any form. When using it in this way, the same grammatical rules apply: use no to modify a noun, or use desu to make it a statement.

Furthermore, 〜付き can be used with verbs in their stem form, though this is less common for B1 learners and more of a specialized usage. For example, fuda-tsuki (labeled/notorious) uses the noun fuda (tag/label). However, the most frequent use remains with nouns. When constructing sentences, pay attention to the particle that follows 〜付き. If it's at the end of a clause, it might be followed by de to indicate a state or reason. Kagu-tsuki de kariru (to rent with furniture). Here, de functions as a state marker. This flexibility allows 〜付き to integrate seamlessly into various grammatical structures, whether you are describing a state, a reason, or a specific characteristic of an object. As you practice, try to identify 〜付き in the wild—on posters, in advertisements, and in dialogue—to see how native speakers manipulate these patterns to convey maximum information with minimum effort.

Advanced Pattern

[Noun] 付き で [Verb] (Doing something in the state of having [Noun] attached/included.)

In summary, the use of 〜付き in sentences is characterized by its ability to transform simple nouns into descriptive adjectives or predicates. Whether you are describing a physical object like a 'roofed' (yane-tsuki) parking lot or an abstract concept like a 'guaranteed' (hoshou-tsuki) success, the underlying logic remains the same. It is a tool for bundling information, making your Japanese more concise and professional. By practicing both the predicate form and the noun-modifying form, you will gain a significant advantage in both comprehension and expression, allowing you to handle complex descriptions with ease. Always remember to check if the 'attachment' is a physical part of the object or a separate item included in a set, as this will help you choose the most appropriate nouns to pair with this powerful suffix.

The word 〜付き (tsuki) is ubiquitous in Japanese society, and you will hear it in a wide variety of contexts, ranging from the highly formal to the casual everyday. One of the most common places to encounter it is in the realm of consumer electronics and technology. When browsing for a new smartphone, laptop, or camera, the specifications will almost always use 〜付き to denote built-in features. For example, a laptop might be described as ka-me-ra-tsuki (camera-equipped) or mausu-tsuki (comes with a mouse). In these contexts, it serves as a technical specification that clarifies what the consumer is purchasing. You'll hear sales clerks using it to highlight the value of a product: "This model is hoshou-tsuki (with warranty), so it's very popular." This usage is direct, informative, and essential for making informed purchasing decisions in Japan's highly detailed retail environment.

Retail Context

Used to list included accessories or built-in hardware features.

Real Estate Context

Used to describe amenities like 'furnished,' 'with parking,' or 'with internet.'

Another major arena for 〜付き is real estate and housing. If you've ever looked at a Japanese apartment listing (known as a 'bukken'), you've seen this suffix dozens of times. A kagu-tsuki (furnished) apartment is a common search term for expatriates and students. Similarly, chuushajou-tsuki (with parking) or auto-rokku-tsuki (with auto-lock security) are standard terms used to describe the features of a property. Real estate agents will use these terms constantly when showing properties to prospective tenants. Hearing "This room is eakon-tsuki (with air conditioning)" is a crucial piece of information in the humid Japanese summers. In this context, 〜付き isn't just a grammatical point; it's a vital piece of data that determines the livability and price of a home. The suffix provides a quick, standardized way to communicate the 'added value' of a property.

In the service and hospitality industry, 〜付き is equally prominent. When you visit a restaurant, especially for lunch, you will often see 'sets' that are dorinku-tsuki (with a drink) or sarada-tsuki (with a salad). Waitstaff will often confirm your order by saying, "This set is kōhī-tsuki (includes coffee), is that alright?" In hotels and traditional inns (ryokan), room plans are categorized by their inclusions: ni-shoku-tsuki (with two meals) or rotenburo-tsuki (with an open-air bath). These phrases are part of the standard vocabulary of travel and dining in Japan. They help set expectations and ensure that the guest knows exactly what is included in their experience. For a traveler, recognizing these terms is the difference between a smooth trip and a confusing one. The suffix acts as a clear marker of the 'omotenashi' (hospitality) being offered.

Beyond commercial settings, 〜付き also appears in social and idiomatic expressions. You might hear someone described as un-tsuki (lucky) or sensu-tsuki (having good sense/style). While these are slightly more figurative, they follow the same logic: the quality (luck or sense) is 'attached' to the person. In the workplace, you might hear about a jouken-tsuki (conditional) contract or a shounin-tsuki (with approval) document. Even in the world of entertainment, you'll see tokuten-tsuki (with special bonus/limited edition) CDs or DVDs. Whether you are reading a business email, watching a commercial, or ordering food, 〜付き is a constant companion in the Japanese linguistic landscape. It is a word that bridges the gap between the physical world of objects and the abstract world of services and qualities, making it one of the most useful suffixes to master for any student of the language.

Daily Life Context

Found on product packaging, menus, and in verbal confirmations of services.

Professional Context

Used in contracts, agreements, and to describe the status of projects or approvals.

In conclusion, the 'where' of 〜付き is essentially 'everywhere.' Its utility in providing clear, concise information about inclusions makes it a staple of Japanese communication. By paying attention to this suffix in different environments, you will not only improve your vocabulary but also gain a deeper understanding of how Japanese people communicate value and expectations. From the 'with rice' of a simple meal to the 'with conditions' of a complex legal agreement, 〜付き is a small but mighty suffix that carries a lot of weight in everyday life. As you continue your studies, keep your ears open for this word, and you'll soon realize just how fundamental it is to the way the Japanese language describes the world of things and services.

While 〜付き (tsuki) is a relatively straightforward suffix, there are several common pitfalls that learners often encounter. One of the most frequent mistakes is confusing 〜付き with the verb 付く (tsuku) or 付ける (tsukeru). While they share the same root, their grammatical functions are distinct. Learners sometimes try to use tsuki as a standalone verb in a way that doesn't fit the suffixal structure. For example, saying *kagu o tsuki desu instead of kagu-tsuki desu is a common error. The suffix 〜付き must be directly attached to the noun it describes as being included. It does not take the particle o because it is not acting as a direct object in that specific construction; rather, it is forming a compound noun or a predicate that describes the state of the subject.

Mistake 1: Particle Misuse

Using 'o' before 'tsuki' (e.g., *choushoku o tsuki) instead of attaching it directly (choushoku-tsuki).

Mistake 2: Confusing with 'Iri' (入り)

Using 'tsuki' for things inside a container when 'iri' is more appropriate.

Another common point of confusion is the distinction between 〜付き and 〜入り (iri). Both can be translated as 'with' or 'including' in English, but they are used differently in Japanese. 〜付き generally refers to an attachment or an inclusion of a separate item (like a room with breakfast, or a phone with a camera). In contrast, 〜入り usually refers to something being inside or contained within something else, often a liquid or a mixture. For example, coffee with milk is miruku-iri (milk-in), not miruku-tsuki (which would imply a separate carton of milk on the side). Using tsuki when iri is expected can sound unnatural to native speakers, as it suggests a physical attachment rather than a mixture or containment. Understanding this subtle difference is key to achieving a more natural level of Japanese.

A third mistake involves the misuse of the particle 'no' when modifying other nouns. As mentioned in the grammar section, if you want to use 〜付き to describe another noun, you must use no. A common error is saying *kamera-tsuki keitai instead of kamera-tsuki no keitai. While some compound words are so common that the no is dropped in casual speech or on signs (like kamera-tsuki keitai actually being a common compound), for a learner, it is safer and more grammatically correct to include the no. This ensures that the relationship between the 'feature-included' state and the object being described is clear. Furthermore, learners sometimes forget that 〜付き is a suffix and try to use it as a standalone word. You cannot simply say *Tsuki desu to mean 'It's included.' You must specify what is included (e.g., Muryou-tsuki desu - It's free-included, though muryou desu is more common).

Additionally, there is the formality and register issue. While 〜付き is widely used, in extremely formal legal or academic documents, other terms like fuzui (附随 - incidental/accompanying) or doufu (同封 - enclosed) might be more appropriate. Using 〜付き in a very high-level legal contract might come across as slightly too casual or imprecise. However, for B1 and even B2 levels, 〜付き is perfectly acceptable for most business and daily life situations. Finally, be careful with animate vs. inanimate objects. We generally don't use 〜付き to describe people being with other people (e.g., *tomodachi-tsuki). Instead, we use to issho ni (together with) or zure (accompanied by, as in kazoku-zure). Using 〜付き for people can sound like you are treating the person as an accessory or a feature of an object, which can be unintentionally rude or humorous.

Mistake 3: Animacy Error

Applying 'tsuki' to human companions instead of using 'issho ni' or 'zure'.

Mistake 4: Over-reliance

Using 'tsuki' for every 'with' in English, failing to recognize when 'de' or 'to' is better.

In conclusion, while 〜付き is a powerful and common tool, it requires careful application. By avoiding the confusion with similar-sounding verbs, distinguishing it from 'containment' suffixes like iri, ensuring correct particle usage with no, and respecting the animacy of the subjects, you will avoid the most common errors made by intermediate learners. Paying attention to these nuances will not only make your Japanese more accurate but also demonstrate a deeper understanding of the logic behind Japanese word formation. Practice using 〜付き in various contexts, but always double-check if the 'attachment' is appropriate for the situation. With time and exposure, the correct usage will become second nature, and you'll be able to describe complex 'package deals' with the precision of a native speaker.

To truly master 〜付き (tsuki), it is essential to understand the landscape of similar words and alternatives that also convey the idea of 'with' or 'including.' The Japanese language is rich with suffixes and particles that describe the relationship between objects, and choosing the right one depends on the nature of the inclusion. One of the closest relatives is 〜入り (iri), which we've touched upon. While tsuki implies an attachment or an external inclusion, iri implies that something is inside or part of the composition. For example, a box of chocolates with nuts inside is natsu-iri (nuts-in). Understanding this 'inside vs. outside' or 'composition vs. accessory' distinction is the first step in differentiating these two common suffixes.

〜入り (iri)

Focuses on containment or being an ingredient (e.g., milk in coffee, nuts in chocolate).

〜込み (komi)

Focuses on the total price or a comprehensive inclusion (e.g., tax included, shipping included).

Another important alternative is 〜込み (komi), often seen in the phrase zei-komi (tax included). While tsuki describes an item or service that is added to another, komi focuses on the idea of something being 'folded into' or 'accounted for' in a total. You will see komi most frequently in financial contexts, such as souryou-komi (shipping included in the price). If you use tsuki for tax, like *zei-tsuki, it sounds like the tax is a separate physical object attached to the price, which is conceptually odd. Therefore, use komi when talking about totals and tsuki when talking about additional features or physical attachments. This distinction is vital for clear communication in commercial and financial transactions in Japan.

For describing people or groups, as mentioned before, 〜連れ (zure) is the appropriate suffix. If you see a sign that says kazoku-zure kangei, it means 'families (with children) welcome.' Using tsuki here would be dehumanizing. Similarly, douhan (同伴) is used for 'accompanied by' in more formal or specific social contexts (like a 'date' or a business companion). In the realm of formal documents, 同封 (doufuu) is used for things 'enclosed' in an envelope, and 添付 (tenpu) is used for 'attaching' files to an email. While tenpu and tsuki share the same kanji (付), tenpu is a formal Sino-Japanese (kango) verb, whereas tsuki is a more versatile native Japanese (wago) suffix. Knowing when to switch from the everyday tsuki to the professional tenpu is a hallmark of an advanced learner.

Finally, let's consider the simple particle 〜と (to). In many cases, you can simply say [Noun A] to [Noun B] to mean 'A and B.' However, to is neutral and doesn't imply that one is a feature of the other. Raisu to sūpu (rice and soup) just lists two items. Sūpu-tsuki no raisu (rice with soup included) suggests that the soup is an addition to the main rice dish. The choice between to and tsuki depends on whether you want to present the items as equals or as a primary item with an added feature. By understanding these alternatives—iri, komi, zure, doufuu, tenpu, and to—you can navigate the complexities of Japanese 'inclusions' with precision and grace, ensuring that your meaning is always clear and culturally appropriate.

〜付き vs. 〜と

'Tsuki' implies a hierarchical relationship (feature added to main), while 'to' implies equality.

〜付き vs. 〜添付

'Tsuki' is a general suffix; 'Tenpu' is a specific formal verb for digital or physical document attachment.

In summary, while 〜付き is a highly useful and common suffix, it is just one part of a larger system of expressing inclusion and attachment in Japanese. By learning its synonyms and alternatives, you gain the ability to choose the exact word that fits the context—whether you're talking about the ingredients in your food, the tax in your bill, the companion on your trip, or the file in your email. This level of precision is what separates an intermediate learner from a truly proficient speaker. As you continue to encounter these words, pay close attention to the context and the 'nature' of the attachment, and you'll soon find yourself choosing the right word instinctively every time.
