Mastering the clock and the calendar is the bedrock of scheduling meetings, making plans with friends, and navigating daily life in Japan. In this lesson, we will decode the Japanese time system and master the days of the week, moving beyond simple phrases into functional communication.
Telling time in Japanese relies on two distinct counters: ji for hours and fun/pun for minutes. While the hour counter is straightforward, the minute counter is phonologically dependent on the number it follows.
The hours (1–12) are expressed by adding ji after the number. Crucially, 4 o'clock is yo-ji, 7 o'clock is shichi-ji, and 9 o'clock is ku-ji. For minutes, we use fun or pun. The distinction depends on the preceding sound: numbers ending in 0, 1, 3, 4, 6, and 8 generally use pun or its variations (e.g., san-pun for 3 minutes, roppun for 6 minutes).
Important Note: 30 minutes is often expressed as han (half). For example, 2:30 is ni-ji han.
The Japanese week is rooted in the elemental system of nature. Each day ends with youbi, meaning "day of the week." Learning these is a matter of memorizing the prefix for each element:
These are used as nouns. To say "on Monday," you simply add the particle ni after the day: Getsuyoubi ni.
When planning your day, you often need to express duration or reference specific times relative to now. The word han for "half-past" is incredibly common. To express "from X to Y," we use the particles kara (from) and made (until).
For example, "From 9:00 until 5:00" is ku-ji kara go-ji made. This structure is essential for professional and social planning. If you want to clarify the time of day—such as morning, afternoon, or evening—place these time indicators at the start of your sentence. Gozen covers the morning (A.M.), and gogo covers the afternoon/evening (P.M.).
A frequent mistake beginners make is confusing the kanji for days of the week or slipping into English counting patterns. Japanese time is strictly additive, whereas English often uses "quarter till" or "twenty to." In Japanese, you always state the hour, then the minutes. You never drop the hour even if it is implied by context.
Additionally, pay attention to the intensity of your speech. When making plans, ending a sentence with desu ka? makes it a polite question, while desu makes it a statement.
