The Number System of Ancient Japanese


The number system of ancient Japanese is not used now except 1 through 10, which are sometimes used as alternate vocabulary. Modern Japanese uses a different number system imported from Chinese. The Modern column below means the modern pronunciation of ancient Japanese numbers.

Note:
The suffixes "tu", "ti", and "di" (modern "tsu", "chi", and "ji") were used to count general objects. This is similar to the number system of Ainu.

32 years = misotose amari putatose

The conjunction "amari" sometimes became "mari".
ex.
32 = misodi amari putatu = misodimari putatu
