来週

The Japanese word 来週 (らいしゅう - raishuu) is a fundamental temporal noun that translates directly to 'next week' in English. It is composed of two distinct kanji characters: 来 (rai), which means 'to come' or 'future,' and 週 (shuu), which means 'week.' Together, they literally describe the 'coming week.' This word is essential for anyone navigating daily life, business, or social arrangements in Japan, as it serves as the primary anchor for planning events that occur in the immediate seven-day period following the current one. Unlike some languages where 'next week' might be ambiguous—sometimes referring to the week starting this coming Sunday or the week after—in Japanese, raishuu consistently refers to the very next seven-day block starting from the next Monday (or Sunday, depending on the calendar convention, though Monday is the standard start of the work week in Japan).

Temporal Relativity

Raishuu is a relative time noun, meaning its specific dates change depending on when you say it. If you say it on a Friday, it refers to the days just a few days away. If you say it on a Monday, it refers to the period starting seven days later.

In a cultural context, Japanese society is highly organized around weekly schedules, particularly in the education and corporate sectors. Whether you are scheduling a doctor's appointment, a business meeting, or a casual dinner with friends, 来週 will be one of your most frequently used words. It is often paired with specific days of the week to narrow down the timing, such as raishuu no getsuyoubi (next Monday).

Grammatical Flexibility

Raishuu can function as both a noun and an adverb. When used adverbially, it does not require the particle 'ni' to indicate time, though 'ni' can be added for specific emphasis on the target week.

Furthermore, understanding 来週 allows you to grasp the pattern of Japanese time-keeping. It belongs to a family of words including senshuu (last week), konshuu (this week), and saraishuu (the week after next). Mastering this sequence is a major milestone for A2 learners as it unlocks the ability to discuss future plans with precision. In professional settings, using raishuu correctly is vital for deadline management and project coordination.

Kanji Breakdown

The kanji 'Rai' (来) appears in many future-oriented words like 'Rainen' (next year) and 'Raigetsu' (next month), making it a powerful root for vocabulary expansion.

Using 来週 in a sentence is relatively straightforward because it behaves much like 'next week' in English, but with specific Japanese particle rules. The most common way to use it is as a time adverb at the beginning of a sentence to set the temporal context. For example, 'Raishuu, nihon ni ikimasu' (Next week, I will go to Japan). Unlike specific dates or times (like 'at 3 o'clock'), relative time nouns like raishuu do not strictly require the particle に (ni), though adding it is not grammatically incorrect and can provide a sense of 'during' or 'in' the next week.

With Particles

Common particle pairings include 'raishuu no' (next week's), 'raishuu kara' (from next week), and 'raishuu made' (until next week). These allow for complex scheduling descriptions.

When you want to specify a particular day within next week, you use the particle の (no) to link raishuu with the day. For instance, raishuu no kanyoubi means 'next Tuesday.' This structure is essential for making specific appointments. In Japanese, the larger unit of time always comes first, followed by the smaller unit, which is the opposite of the common English 'Tuesday of next week' structure.

In polite Japanese (Desu/Masu form), raishuu is often used to express intentions or future states. Because Japanese does not have a distinct future tense (it uses the non-past tense), the inclusion of raishuu is the primary indicator that the action has not happened yet. Without such a time marker, a sentence like 'Iki-masu' could mean 'I go' (habitual) or 'I will go.' Adding raishuu clarifies the intent immediately.

Sentence Placement

While usually placed at the start, it can also appear right before the verb for emphasis. However, placing it at the start is the most natural way to frame a conversation about the future.

For advanced usage, raishuu can be modified by adjectives or other nouns to describe the nature of the week. For example, isogashii raishuu (a busy next week). In business emails, it is common to see phrases like raishuu no go-yotei (your schedule for next week), where the honorific 'go' is added to 'yotei' (plan/schedule) to show respect to the recipient.

Common Combinations

'Raishuu no koto' (matters regarding next week), 'Raishuu chuu' (during next week/by the end of next week).

You will encounter 来週 in almost every facet of Japanese life. In the workplace, it is the heartbeat of project management. During the 'asa-rei' (morning meeting), managers will often outline the goals for raishuu. You will hear it in phrases like 'Raishuu no kaigi' (next week's meeting) or 'Raishuu no shimekiri' (next week's deadline). In these contexts, the word carries a sense of preparation and forward-looking responsibility.

In the media, weather forecasters use raishuu constantly to predict upcoming patterns. A typical weather report might say, 'Raishuu wa zenkokuteki ni harete, kion ga agaru deshou' (Next week will be sunny nationwide, and temperatures will likely rise). Similarly, news broadcasts use it to announce upcoming political events, festivals, or public holidays. If you are watching a TV drama, characters will use raishuu to make plans to meet, resolve conflicts, or set the stage for the next episode's cliffhanger.

In Education

Teachers use 'raishuu' to announce homework, exams, or school events. 'Raishuu wa shiken ga arimasu' (There is an exam next week) is a phrase every student in Japan knows well.

In casual social settings, raishuu is the go-to word for making plans. Friends might ask, 'Raishuu, hima?' (Are you free next week?) or 'Raishuu, asobi ni ikanai?' (Want to go out next week?). It is also used in the common parting phrase 'Mata raishuu!' (See you next week!), which is frequently heard at the end of classes, weekly clubs, or work shifts.

Retail and service industries also utilize raishuu for promotions. You might see signs in shop windows saying 'Raishuu kara se-ru kaishi!' (Sale starts from next week!). In restaurants, staff might mention that a certain seasonal dish will be available raishuu kara. Essentially, if something is happening in the near future but not immediately today or tomorrow, raishuu is the most likely word you will hear to describe that timeframe.

Public Announcements

Train stations and public offices use 'raishuu' to announce maintenance or holiday closures. 'Raishuu no getsuyoubi wa kyuukan desu' (Next Monday is a holiday/closed day).

One of the most frequent mistakes English speakers make when using 来週 is the unnecessary use of the particle に (ni). In English, we say 'I'm going next week,' without a preposition. In Japanese, raishuu acts as a relative time noun (like kyou for today or ashita for tomorrow). While adding 'ni' isn't always 'wrong,' it can sound unnatural or overly emphatic if used in every sentence. Beginners often try to translate 'in next week' literally, which leads to 'raishuu ni,' whereas a simple 'raishuu' is usually more native-sounding.

The 'No' Particle Confusion

Another common error is forgetting the 'no' particle when specifying a day. Saying 'Raishuu getsuyoubi' is understandable but sounds 'broken.' The correct form is 'Raishuu no getsuyoubi.'

Another mistake involves confusing raishuu with raigetsu (next month) or rainen (next year). Because they all start with the same 'rai' sound, learners often mix them up during fast-paced conversations. It is crucial to drill the 'shuu' (week), 'getsu' (month), and 'nen' (year) suffixes separately to avoid scheduling disasters. Imagine telling a boss you'll finish a report raishuu (next week) when you actually meant raigetsu (next month)!

Learners also struggle with the boundary of raishuu. If it is currently Sunday, does raishuu refer to the week starting tomorrow (Monday) or the week after? In Japan, the standard interpretation is that raishuu starts on the very next Monday. However, if you are speaking on a Sunday, some might clarify by saying ashita kara no shuu (the week starting tomorrow). Misunderstanding this boundary can lead to missed appointments.

Mixing Up 'Raishuu' and 'Saraishuu'

'Saraishuu' means 'the week after next.' Beginners sometimes use 'raishuu' twice or try to say 'tsugi no raishuu,' which is redundant and incorrect. Use 'saraishuu' for two weeks out.

Finally, there is the issue of formality. While raishuu is perfectly acceptable in business, in extremely formal or written contexts, one might use jishuu (次週). Using raishuu in a highly formal legal document might be seen as slightly too casual, though this is a nuance mostly relevant for C1/C2 learners. For A2 learners, the main focus should be on the 'no' particle and avoiding the 'ni' particle trap.

While 来週 is the most common way to say 'next week,' there are several other terms that might be used depending on the context, formality, or specific timeframe being discussed. Understanding these nuances helps you sound more like a native speaker and allows you to interpret different types of Japanese media more accurately.

次週 (じしゅう - Jishuu)

This is a more formal or technical term for 'the following week.' You will often see this in TV schedules ('Jishuu no housou' - next week's broadcast) or in business reports. It is less common in casual conversation.

再来週 (さらいしゅう - Saraishuu)

This means 'the week after next' (two weeks from now). It is an essential companion to 'raishuu' for planning further into the future.

翌週 (よくしゅう - Yokushuu)

This means 'the following week' relative to a specific point in the past or future, rather than relative to 'now.' For example, 'The event happened, and the following week (yokushuu), we cleaned up.'

In some contexts, people might use tsugi no shuu (次の週), which literally means 'the next week.' This is often used when explaining a sequence of events, such as 'We will do A in the first week, and B in the next week (tsugi no shuu).' It feels slightly more descriptive and less like a fixed time label than raishuu.

When comparing raishuu with its counterparts, it's helpful to look at the whole 'week' family. Senshuu (last week) and Konshuu (this week) are the most immediate points of comparison. In a business meeting, you might hear a summary like: 'Senshuu did this, konshuu we are doing this, and raishuu we will do that.' This logical progression is the backbone of Japanese project reporting.

For very specific timeframes, you might also hear shuu-ake (週明け), which means 'the beginning of the week' (usually Monday morning). If someone says they will contact you raishuu no shuu-ake, they specifically mean next Monday morning. This is a very common business term that adds more precision than just saying raishuu.
