Japanese numbers look simple at first: ichi, ni, san, yon, go, roku, nana, hachi, kyuu, juu. The part that confuses beginners is what happens after the first ten numbers. You also need native object counting words such as hitotsu and futatsu, common counters such as hon, mai, satsu, nin, and ko, and time expressions such as ichiji, niji, sanji, and han. This trainer keeps those ideas together so you can study numbers as a real communication skill, not as an isolated list.

For JLPT N5 and early N4 study, numbers appear in prices, time, age, dates, addresses, phone numbers, classroom instructions, shopping conversations, train schedules, and reading passages. A learner who can only count from one to ten may still struggle when a question asks about three books, two people, 8:30, or 1,200 yen. Use the tabs below to move from basic number recognition into practical counting patterns.

The best routine is simple: type a number, read the Japanese aloud, listen to the audio, and then make a short phrase. For example, after practicing san, say san-nin for three people, san-satsu for three books, and sanji for three o'clock. When you connect a number with a real counter, the word becomes easier to remember because it has a purpose.
