Numbers had already been introduced;
1 : one => Ichi
2 : two => Ni
3 : three => San
—
10 : ten => Juu
In addition to these numbers, there is another numbering system in Japanese that is used when you counting some objects;
1 : there is one object => Hitotsu
2 : there are two objects => Futatsu
3 : there are three objects => Mittsu
4 : there are four objects => Yottsu
5 : five => Itsutsu
6 : six => Muttsu
7 : seven => Nanatsu
8 : eight => Yattsu
9 : nine => Kokonotsu
10 : ten => To’o
Practice and remember the following conversation;
A : Ringo ga Ikutsu Arimasuka. (How many apples are there?)
B : Ringo ga Yottsu Arimasu. (There are four apples.)
