Japanese Numbers

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 number-related 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 number-related expressions are based on this set. For example, this set is used as the base of the Japanese counting system.

e.g. 400=yon-hyaku, 700=nana-hyaku, 900=kyuu-hyaku

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 time-related expressions are based on this set.

e.g. April(4)=shi-gatsu, July(7)=shichi-gatsu, September(9)=ku-gatsu,
7 o'clock=shichi-ji, 9 o'clock=ku-ji

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: NOUN-o 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.
