〜時

§ Basic Use of ~時 (ji)

The Japanese suffix 〜時 (ji) is essential for telling time. It directly translates to 'o'clock' when attached to a number. It's a fundamental piece of vocabulary you'll use constantly in daily conversations, whether you're arranging a meeting, asking for train times, or just planning your day.

Definition

Suffix for hours (e.g., 3時 - three o'clock).

You simply attach 〜時 (ji) to the number representing the hour. For example:

• 1時 (ichi-ji): One o'clock
• 2時 (ni-ji): Two o'clock
• 3時 (san-ji): Three o'clock
• 4時 (yo-ji): Four o'clock (Note: not 'yon-ji')
• 5時 (go-ji): Five o'clock
• 6時 (roku-ji): Six o'clock
• 7時 (shichi-ji): Seven o'clock (Note: not 'nana-ji' for time, usually)
• 8時 (hachi-ji): Eight o'clock
• 9時 (ku-ji): Nine o'clock (Note: not 'kyuu-ji')
• 10時 (juu-ji): Ten o'clock
• 11時 (juuichi-ji): Eleven o'clock
• 12時 (juuni-ji): Twelve o'clock

§ Hearing ~時 (ji) at Work

In a Japanese work environment, precision is valued, and that includes time. You'll hear 〜時 (ji) constantly for meeting times, deadlines, and schedules.

§ Hearing ~時 (ji) at School

School schedules are rigid, so expect to hear 〜時 (ji) frequently for class times, club activities, and school events.

§ Hearing ~時 (ji) in the News

News broadcasts often report times for events, broadcasts, or deadlines. You'll hear 〜時 (ji) used to convey this information clearly and concisely.

§ Daily Life and Conversations

Beyond formal settings, 〜時 (ji) is indispensable for everyday interactions, from making plans with friends to checking public transport schedules.

Mastering 〜時 (ji) is one of the first and most practical steps in becoming comfortable with spoken Japanese. Practice saying the times out loud until they become second nature.

§ Don't confuse it with 'time' (時間 - jikan)

One of the most common mistakes beginners make is confusing 〜時 (ji), which refers specifically to hours on a clock, with 時間 (jikan), which means 'time' in a general sense or a duration of time. While both involve 'time', their usage is very different.

DEFINITION

〜時 (ji): Suffix for specific hours (e.g., 3時 - three o'clock).

DEFINITION

時間 (jikan): General 'time' or 'duration of time' (e.g., 2時間 - two hours long).

You use 〜時 (ji) when you are telling someone what time it is, or when something will happen at a specific hour.

On the other hand, you use 時間 (jikan) when you're talking about how long something takes.

§ Irregularities in counting hours

Another common pitfall is forgetting the irregular readings for certain hours. While most numbers simply attach to 〜時 (ji), some change their pronunciation.

• 4時 (yo-ji): Not 'yon-ji'.

• 7時 (shichi-ji): While 'nana-ji' is sometimes heard, 'shichi-ji' is the more common and formal way.

• 9時 (ku-ji): Not 'kyū-ji'.

Let's look at examples for these irregular hours.

§ Don't forget 'han' (half) for thirty minutes

When expressing 'half past' an hour, Japanese uses 〜半 (han). It's a quick way to say 'thirty minutes past' without explicitly stating the minutes.

DEFINITION

〜半 (han): Half past the hour (e.g., ３時半 - three thirty).

Many learners, when trying to say 'three thirty', might try to say 'san-ji san-jū-pun', which is grammatically correct but less natural. The more common and natural way is to use 〜半 (han).

§ Understanding 時 (じ) for Hours

The Japanese suffix 〜時 (じ) is straightforward. It's used to tell time, specifically when referring to the hour. Think of it like adding "o'clock" in English. When you want to say "one o'clock," you say 一時 (いちじ). For "two o'clock," it's 二時 (にじ), and so on. It's a fundamental part of telling time in Japanese, so mastering it is essential.

DEFINITION

Suffix for hours (e.g., 3時 - three o'clock).

Translation hint: What time is it now?

Translation hint: The meeting starts at three o'clock.

§ 時 (とき) vs. 時 (じ) for Time

This is where it can get a little tricky for learners. Both 時 (とき) and 時 (じ) relate to time, but they have distinct uses. Let's break it down:

• 時 (じ): This is the suffix we've been discussing. It specifically refers to clock hours. You attach it to a number to indicate a specific time on the clock.
• 時 (とき): This word means "when," "at the time of," "occasion," or "moment." It's more about a general point in time, a period, or a specific instance, rather than a precise hour on the clock. It can be used as a noun on its own or attached to verbs and adjectives to create clauses that indicate when something happens.

Think of it this way:

• If you're answering "What time is it?" you'll use 〜時 (じ).
• If you're answering "When did that happen?" or describing "the time when..." you'll likely use 時 (とき).

Translation hint: When I was a child, I often played in the park. (Here, 時 refers to a period of life, not a clock hour.)

Translation hint: When I was going home, it was raining. (Here, 時 indicates the specific moment or period of returning home.)

§ Other Time-Related Words

While 時 (じ) is for hours, Japanese has other specific words for different units of time:

• 分 (ふん/ぷん): This is for minutes. For example, 5分 (ごふん - five minutes), 10分 (じゅっぷん - ten minutes).
• 秒 (びょう): This is for seconds. For example, 30秒 (さんじゅうびょう - thirty seconds).
• 時間 (じかん): This means "hour(s)" as a duration. For example, 1時間 (いちじかん - one hour) to describe how long something takes. Don't confuse this with 一時 (いちじ - one o'clock).
• 日 (にち): This is for days. For example, 3日 (みっか - three days).
• 週 (しゅう): This is for weeks. For example, 2週間 (にしゅうかん - two weeks).
• 月 (つき/げつ): This is for months. For example, 1ヶ月 (いっかげつ - one month).
• 年 (ねん/とし): This is for years. For example, 2年 (にねん - two years).

Understanding the difference between 時 (じ) and 時間 (じかん) is crucial. 時 (じ) tells you *when* something happens on the clock, while 時間 (じかん) tells you *how long* something takes.

Translation hint: The movie takes two hours. (Here, 時間 refers to the duration.)

Translation hint: He studies Japanese for three hours every day.

By keeping these distinctions in mind, you'll avoid common mistakes and express yourself more accurately when talking about time in Japanese.
