Japanese counting can feel overwhelming because, unlike English, you don't just add a "s" to the end of a word to make it plural. You use counters, which are specific words attached to numbers that tell us what kind of object is being counted! By the end of this lesson, you will be able to confidently count basic objects and people.
Before you learn how to count things, you must master the fundamental numbers. In Japanese, these are known as ichi, ni, san, yon/shi, go, roku, nana/shichi, hachi, kyuu, juu. Learning these is the bedrock of your fluency.
It is important to note that for numbers 4, 7, and 9, there are multiple pronunciations. For example, 4 is both yon and shi. Yon is generally preferred in counting objects to avoid confusion with shi, which is also the word for "death."
Pay close attention to the rhythm. Japanese is a syllable-timed language, meaning each sound should be given roughly the same amount of time. Practice saying these out loud until they feel as natural as breathing.
When you don't know the specific counter for an item, or when you are counting generic objects like apples, boxes, or even abstract ideas, you use the -tsu counter system. This is unique because it drops the standard number pronunciations for the numbers 1 through 10.
Instead of ichi-tsu, you say hitotsu. Notice how the ending syllable is always -tsu (except for 10).
Note: The -tsu counter is strictly for numbers 1 through 10. You cannot use it for 11 or higher. If you need to count more than 10 of something, you switch to the standard number + the word ko (the general counter for small or round objects).
When counting human beings, the stakes change. You cannot use -tsu or any other object-based counter; you must use the -nin counter. This is one of the most essential skills for navigation and dining in Japan.
For 1 and 2, the pronunciation becomes irregular to make it easier to say:
For the rest, simply take the number and add -nin:
Common pitfall alert: Beginners often try to apply the general numbers to people, saying something like ichinin for "one person." Always remember that for 1 and 2, the irregular forms hitori and futari are mandatory.
When you combine a number and a counter, you are creating a "measure word" structure. In Japanese, this structure functions like an adverbial phrase. If you are pointing at something, you use the structure: [Object] + [Particle] + [Number] + [Counter].
Waitβdid you notice something new? I used issatsu and dai. Just like English has "a loaf of bread" or "a sheet of paper," Japanese uses different counters for flat objects (mai), books (satsu), and machines (dai).
