Japanese Numbers and Counters: The Practical Beginner Guide

Japanese numbers from zero to ten thousand

Numbers between units are additive: 24 is ni-jū yon, and 365 is san-byaku roku-jū go. Japanese groups large numbers around man, ten thousand, so 100,000 is jū-man and 1,000,000 is hyaku-man. Write commas while learning, but mark groups of four digits to train the Japanese rhythm.

Sound changes in hundreds and thousands

These changes make speech easier to pronounce. Learn sanbyaku as one sound pattern, not as a violation of a rule. The same compression and voicing recur with counters, which is why accurate listening practice matters as much as reading a chart.

The general counter from one to ten

This native-Japanese series is useful for many ordinary objects and servings when no more specific counter is necessary. It stops at ten. In a restaurant, biiru o futatsu onegaishimasu is an easy, natural way to request two beers, even though a more specialised counter exists.

The most useful counters

Notice that 本 changes among hon, bon, and pon. People begin with hitori and futari rather than ichi-nin and ni-nin. Ask quantities with nan plus the counter—nan-mai, nan-bon, nan-nin—and learn the question beside the answers.

Time, age, and dates

Clock hours use ji: ichi-ji, ni-ji, san-ji, but four o'clock is yo-ji, seven is shichi-ji, and nine is ku-ji. Minutes use fun or pun: ippun, ni-fun, san-pun, yon-pun, go-fun, roppun, nana-fun, happun, kyū-fun, juppun. Half past is han, so shichi-ji han is 7:30.

Age uses sai, with one year old issai, eight hassai, ten jussai, and twenty hatachi. Calendar days have many traditional readings: tsuitachi for the first, futsuka for the second, through tōka for the tenth, plus jūyokka for the fourteenth and hatsuka for the twentieth. Learn dates as appointment phrases, not one giant isolated list.

Shopping and travel phrases with numbers

A better way to memorise counters

Start from situations, not a dictionary of hundreds of counters. For travel, you need people, tickets, time, dates, floors, nights, and servings. For an office, add documents, machines, and occurrences. Put real nouns and quantities into sentences, then change the number while preserving the rest of the scene.

Practise listening with unpredictable numbers because recognition often lags behind production. Ask a tutor to state prices, times, and party sizes and answer a question about each. When you make a sound-change error, repeat the complete unit—sanbon, not just bon—so the correct rhythm becomes one memory.
