There are two numerical systems in the Japanese language.
The ichi, ni, san system and the hitotsu, futatsu, mittsu system.
The ichi-system is used with number counters. The hitotsu-system is used independently without number counters (ex. 1-en, 1-mai, 1-dai).
The hitotsu-system goes as far as 10 and cannot be use for people, time and money.
