Japanese Counters for Objects - Mai, Hon, Ko
Three object counters cover most everyday needs: 枚 (mai) for flat thin objects, 本 (hon) for long thin objects, and 個 (ko) for small compact objects. Together they handle perhaps 70% of all object-counting situations.
Flat, thin objects: paper, plates, T-shirts, tickets, photos, cards.

Choosing between 〜つ, 〜個, and a specific counter
- 〜つ: native, 1 to 10 only, totally general, slightly informal.
- 〜個: Sino, any number, small compact objects.
- Specific (〜本, 〜枚, etc.): when the object clearly fits a category.
In casual speech, 〜つ and 〜個 are often interchangeable for small objects. Both りんごを三つください (mittsu) and りんごを三個ください (san-ko) are correct for "three apples please".
Frequently asked questions
What is the easiest Japanese object counter to learn first?
〜枚 (mai). It is fully regular with no sound-changes, and covers an enormous category: paper, plates, T-shirts, tickets, cards, photos, pancakes, slices of bread, blankets, CDs. Start with mai before tackling hon and ko.
When do I use 〜本 (hon)?
For long, thin objects: pencils, pens, bottles, umbrellas, trees, neckties, bananas, and (counterintuitively) trains and legs. Sound-changes: ip-pon (1), san-bon (3, rendaku), rop-pon (6), hap-pon (8), jup-pon (10). All others are regular: ni-hon, yon-hon, go-hon, nana-hon, kyū-hon.
Can I use 〜つ instead of a specific counter?
Yes, for objects 1 to 10. 〜つ uses the native readings: hitotsu, futatsu, mittsu. After 10 you must switch to a specific counter (or 〜個 ko, the Sino general). In casual speech, 〜つ and 〜個 are often interchangeable for small objects.
What if I use the wrong counter for an object?
You will be understood. Native speakers may notice and gently correct you. Common errors are not embarrassing. The safe defaults when uncertain are 〜つ (1-10) and 〜個 (any number, small compact objects).
