人数の数え方
Ninzuu no kazoekata
How to count people — the essential counters
Japanese uses special words for counting people. 1 and 2 are irregular; from 3 onward, use number + 人 (nin). Formal contexts (hotels, restaurants) use 名 (mei) instead of 人. 一人/一名 (hitori/ichimei) = one, 二人/二名 (futari/nimei) = two, 三人/三名 (san-nin/sanmei) = three — 人 is everyday, 名 is formal (hotel/restaurant).
何時ですか？
Nanji desu ka?
What time is it?
時 (ji) = o'clock, 分 (fun) = minutes.
〜時に予約があります
[time] ji ni yoyaku ga arimasu
I have a reservation at [time]
Useful when arriving at a restaurant or hotel.
一人、二人、三人
Hitori, futari, san-nin
One person, two people, three people
The people-counter 人 (nin) is irregular for 1 and 2: 一人 (hitori), 二人 (futari). From three onward it's regular: 三人 (san-nin), 四人 (yo-nin), 五人 (go-nin). Staff use the polite form 〜名様 (-mei-sama) instead, e.g. お一人様 (o-hitori-sama).
一つ、二つ、三つ
Hitotsu, futatsu, mittsu
One, two, three (items)
The generic item-counter つ (tsu) is used for food orders, souvenirs, and other countable objects when you don't know the specific counter: 一つ, 二つ, 三つ, 四つ, 五つ... It stops being used after 十 (too) = 10.
