Here's the basic 1-10:
To count from 11-99, you combine the numbers 1 to 10. For example:
* 11 is ju-ichi (jooo-ee-chee) - 10 (ju) plus 1 (ichi).
* 12 is ju-ni (jooo-nee) - 10 (ju) plus 2 (ni).
* 20 is two sets of ten, so you say "two tens," or 1 ni-ju (nee-jooo).
* 21 is ni-ju-ichi (nee-jooo-ee-chee) - 20 (ni-ju) plus l(ichi).
You can use this pattern to count to kyu-ju-kyu (kyooo-jooo-kyooo; 99, or 9 tens plus 9).
To count over 100, keep using the pattern for numbers 11 to 99:
* 100 is hyaku (hyah-koo), so 200 is ni-hyaku (nee-hyah-koo).
* 1,000 is sen (sehn), so 2,000 is ni-sen (nee-sehn).
Here's a few examples of the higher numbers:
Numbers from 10,000 to 100,000, unlike English, has a special digit name for 10,000: man (mahn). For 50,000, you may want to say go-ju-sen because your mathematical logic is that 50,000 is go-ju (50) of sen (1,000), but the Japanese say go-man (goh-mahn; 50,000). Ten thousand is ichi-man (ee-chee-mahn; 10,000), 20,000 is ni-man (nee-mahn; 20,000), and so on. One-hundred thousand isn't 100 sen (thousand) but 10 man, or ju-man.
