Telling time in Japanese looks intimidating at first, but it follows a logic that is actually cleaner than English once you spot the pattern. Instead of memorizing dozens of random words, you combine a number, a counter for the hour, and a counter for the minutes. In this guide you will learn every reading, the tricky sound changes natives never skip, and practical phrases you can use the moment you land in Tokyo or join your next online lesson.

The Building Blocks of Telling Time in Japanese

Before you tackle a full clock, master the three pieces that make up almost every time expression. Telling time in Japanese relies on stacking these parts together in a fixed order.

• The number — the digits 1–12 that you already study in your first week.
• 時 (ji) — the counter for the hour, equivalent to “o’clock.”
• 分 (fun / pun) — the counter for minutes.

So “3:25” becomes san-ji nijuu-go-fun (三時二十五分): literally “three-hour twenty-five-minute.” If you can count and attach these two counters, you are already most of the way there. If your numbers still feel shaky, review our breakdown of Japanese numbers 1–100 first—everything below builds on them.

How to Say the Hour (時 / Ji)

Adding 時 (ji) to a number gives you the hour. However, Japanese has three irregular readings that trip up nearly every learner, so study these before anything else.

The Three Hours You Must Memorize

Notice the pattern in the irregulars: 4 (yo-ji), 7 (shichi-ji), and 9 (ku-ji). These use older native readings instead of the “textbook” numbers. Natives never say “yon-ji” or “kyuu-ji,” so drilling just these three removes your most common mistake instantly.

Adding Minutes (分 / Fun / Pun)

Minutes use the counter 分, but its sound changes depending on the number in front of it—sometimes “fun,” sometimes “pun.” This consonant shift is the second half of telling time in Japanese, and the table below covers every base reading from 1 to 10.

For numbers above ten, simply combine: 25 minutes is nijuu-go-fun, and 38 minutes is sanjuu-hap-pun. The “pun” versions cluster around 1, 3, 4, 6, 8, and 10—say them aloud a few times and the rhythm sticks faster than a chart ever will.

The Shortcut for Half Past

Instead of saying “thirty minutes,” the Japanese often use 半 (han), meaning “half.” So 7:30 is simply shichi-ji han (七時半). It is shorter, more natural, and exactly what you will hear in daily conversation.

Morning, Afternoon, and the 24-Hour Clock

Japan uses both the 12-hour and 24-hour systems, so it helps to know both. To distinguish morning from evening, place the time-of-day word before the hour—the opposite of English word order.

• 午前 (gozen) = AM → gozen shichi-ji (7:00 AM)
• 午後 (gogo) = PM → gogo san-ji (3:00 PM)
• 正午 (shōgo) = noon
• 真夜中 (mayonaka) = midnight

Train stations, TV guides, and official schedules usually prefer the 24-hour clock, so 8:00 PM appears as nijuu-ji (20:00). If you plan to travel, getting comfortable with both formats will save you from missing the last train. For a deeper look at how counters like these work across the language, see the overview of the Japanese counter system on Wikipedia.

How Do You Ask What Time It Is in Japanese?

The single most useful phrase is 今何時ですか？ (Ima nanji desu ka?) — “What time is it now?” Break it down: ima (now) + nanji (what hour) + desu ka (polite question marker).

Here are three practical answers you can model:

1. Ima gozen ku-ji han desu. — It’s 9:30 AM.
2. Gogo yo-ji nijuppun desu. — It’s 4:20 PM.
3. Mou juuni-ji desu yo. — It’s already 12 o’clock!

To ask when something happens, swap in 何時に (nanji ni), as in Eiga wa nanji ni hajimarimasu ka? (“What time does the movie start?”). That tiny particle ni turns a clock reading into a scheduled appointment.

Real-World Examples and a Pro Tip

From years of coaching beginners, I have found that learners remember time best when it is tied to a routine. Instead of reciting the chart, narrate your own day: gozen roku-ji you wake up, gogo ichi-ji you eat lunch, gogo jup-pun sugi you finish work.

Two bonus words make you sound fluent:

• 過ぎ (sugi) = “past” → san-ji go-fun sugi (five past three)
• 前 (mae) = “before / to” → yo-ji juppun mae (ten to four)

My one practical tip: set your phone’s language to Japanese for a week. Seeing the clock labeled in kanji every time you check the time forces dozens of micro-reviews a day—far more effective than a single long study session. When you are ready for guided practice, our Japanese tutors at The Cognitio drill these readings with you until they feel automatic.

Frequently Asked Questions

Why is 4 o’clock “yo-ji” and not “yon-ji”?

The hour counter uses the older native reading “yo” for four, giving yo-ji. This is irregular and does not follow the standard “yon.” The same logic explains “shichi-ji” (7) and “ku-ji” (9), which are the three hours every learner should memorize separately.

What is the difference between “fun” and “pun” for minutes?

Both write the same kanji, 分, but pronunciation shifts for easier speech. You say “pun” after 1, 3, 4, 6, 8, and 10 (ip-pun, san-pun, rop-pun), and “fun” after 2, 5, 7, and 9 (ni-fun, go-fun). It is a sound-change rule, not a meaning change.

Do Japanese people use AM/PM or the 24-hour clock?

Both. Everyday conversation uses 午前 (gozen) and 午後 (gogo) with 12-hour numbers, while timetables, broadcasts, and official documents lean on the 24-hour clock. Knowing both formats is essential for reading train and bus schedules accurately.

How do I say “o’clock” in Japanese?

You attach the counter 時 (ji) directly to the number—there is no separate word for “o’clock.” So “two o’clock” is simply ni-ji. For a full dictionary reference on 時 and its readings, the entry on Wiktionary is a reliable, free resource.
