Japanese Basic Counting System
In the MISJ programs, Japanese numbers are introduced as sets: SET A, B and C.
This makes it easier for you to learn various numberrelated expressions.

NUMBER SET A 

1(ichi) 
2(ni) 
3(san) 
4(yon) 
5(go) 
6(loku) 
7(nana) 
8(hachi) 
9(kyuu) 
10(juu) 
NUMBER SET A is the most important
because more than 80% of numberrelated expressions are based on this set. For example,
this set is used as the base of the Japanese counting system.
e.g. 400=yonhyaku, 700=nanahyaku, 900=kyuuhyaku


NUMBER SET B 

1(ichi) 
2(ni) 
3(san) 
4(shi) 
5(go) 
6(loku) 
7(shichi) 
8(hachi) 
9(ku) 
10(juu) 
Only three numbers, 4, 7 and 9 are different.
Most timerelated expressions are based on this set.
e.g. April(4)=shigatsu, July(7)=shichigatsu, September(9)=kugatsu,
7 o'clock=shichiji, 9 o'clock=kuji


NUMBER SET C 

1(hitotsu) 
2(futatsu) 
3(mittsu) 
4(yottsu) 
5(itsutsu) 
6(muttsu) 
7(nanatsu) 
8(yattsu) 
9(kokonotsu) 
10(too) 
NUMBER SET C is
used to count things except for humans or animals, to order things at a coffee shop
or a restaurant and to state infants' age.
This is the traditional way of counting; however, you can count things only up to ten with this set.
PATTERN: NOUNo SET C kudasai 
This is the pattern for ordering things.
In Japanese, number or quantity information is not an indispensable part of
a sentence and is only added when necessary.
Thus, If the number is not mentioned, it is automatically understood as one.
