The first ten Japanese counters cover ordinary conversation. Past that point the language keeps going, and the second tier is where intermediate learners discover that their confident 匹 was wrong for a horse.
None of these are obscure. They appear in ordinary sentences about shops, streets, animals and buildings.
Animals, sorted by size
| Counter | Reading | Used for | Example |
|---|---|---|---|
| 匹 | hiki | small animals — cats, dogs, fish, insects | 猫三匹 — three cats |
| 頭 | tō | large animals — horses, cattle, elephants | 馬二頭 — two horses |
| 羽 | wa | birds, and by convention rabbits | 鳥五羽 — five birds |
| 尾 | bi | fish, in cooking and fishing contexts | 鯛一尾 — one sea bream |
The 匹 / 頭 boundary is roughly "can you pick it up". A dog is 匹, a cow is 頭, and a large dog sits in a grey area where you will hear both. 頭 literally means head, which is exactly the logic English uses in "fifty head of cattle".
羽 means feather or wing, and its use for rabbits is the piece of trivia every Japanese course eventually mentions. The usual story is that rabbits were counted as birds during periods when eating four-legged animals was frowned upon. Whether that is the true origin is argued over; the usage survives either way, and 匹 is also perfectly normal for a pet rabbit.
Buildings, shops and streets
| Counter | Reading | Used for | Example |
|---|---|---|---|
| 軒 | ken | shops, houses, restaurants | 店三軒 — three shops |
| 棟 | tō | buildings, blocks | ビル二棟 — two buildings |
| 階 | kai | floors of a building | 三階 — third floor |
| 通り | tōri | streets | 二通り — two streets |
| 部屋 | heya | rooms | 四部屋 — four rooms |
軒 is worth learning early because it comes up constantly in directions and recommendations — "there are three ramen places on that street" needs it. It applies to the establishment rather than the building.
Things that come in sets or sequences
| Counter | Reading | Used for | Example |
|---|---|---|---|
| 組 | kumi | pairs, sets, groups of people | 二組 — two pairs |
| 足 | soku | footwear, socks — counted in pairs | 靴一足 — one pair of shoes |
| 着 | chaku | suits and full outfits | スーツ二着 — two suits |
| 膳 | zen | place settings, meals served | 一膳 — one setting |
| 回 | kai | times, occurrences | 三回 — three times |
| 番 | ban | turns, ordinal position | 一番 — first, number one |
足 counts pairs, not items. 靴一足 is one pair of shoes, not one shoe. Japanese has a separate way to talk about a single shoe, and asking a shop assistant for 靴二足 gets you two pairs. The same logic applies to 組 for anything that naturally comes coupled.
The sound changes still apply
The rule from the common counters carries straight over. After 1, 6, 8 and 10 an initial h hardens to p; after 3 it softens to b. Watch 軒:
| # | Japanese | Reading |
|---|---|---|
| 1 | 一軒 | ikken |
| 2 | 二軒 | niken |
| 3 | 三軒 | sangen |
| 6 | 六軒 | rokken |
| 8 | 八軒 | hakken |
| 10 | 十軒 | jukken |
Same shape as 本, 匹 and 杯. Learning the pattern once means you can generate the second tier without memorising it separately, which is the real payoff for having drilled the first ten properly.
How to prioritise
Do not try to learn these as a list. Learn a counter when you meet a noun that needs it, and store the two together — 馬 with 頭, 店 with 軒. A good dictionary entry names the counter, which turns a vocabulary lookup into two facts for the price of one.
And keep the つ series available. Native speakers fall back on it when a counter escapes them or an object resists classification, and there is nothing wrong with doing the same.

Why are rabbits counted with the bird counter in Japanese?
The usual explanation is historical: during periods when eating four-legged animals was discouraged, rabbits were reportedly counted as birds so they could be eaten without breaking the convention. Whether that origin story is accurate is disputed, but the usage is real — 羽 wa does get used for rabbits, alongside the ordinary 匹 hiki.
How many Japanese counters are there in total?
Several hundred, but the distribution is extremely lopsided. Around ten cover most daily conversation, another twenty or so cover most of what you will read, and the remainder are specialist. Learning them by frequency rather than by list is far more efficient.
What happens if I use the wrong counter?
You will usually be understood, and the error is minor compared with a wrong particle or a wrong verb form. Using 匹 for a horse rather than 頭 sounds slightly off, not incomprehensible. The generic つ series is a legitimate fallback for most concrete objects up to ten.
