How to Count in Japanese

Learning numbers and counting in Japanese is simplified because the Japanese number system is quite logical. The entire number system is based on counting the number of tens and then adding the ones. For example, 11 is jū-ichi, which is 10 (jū) plus 1 (ichi). 21 is ni-jū-ichi, which is 2 (ni) times 10 (jū) plus 1 (ichi).
When you're counting numbers in order, you'll use this pronunciation.
