More Numbers 

With "hyaku" (100) and "sen" (1000), the pattern is basically same. However there are some sound change occurred. 

100	hyaku 百	1000	sen 千
200	nihyaku 二百	2000	nisen 二千
300	sanbyaku 三百	3000	sanzen 三千
400	yonhyaku 四百	4000	yonsen 四千
500	gohyaku 五百	5000	gosen 五千
600	roppyaku 六百	6000	rokusen 六千
700	nanahyaku 七百	7000	nanasen 七千
800	happyaku 八百	8000	hassen 八千
900	kyuuhyaku 九百	9000	kyuusen 九千

The Japanese uses 10,000 as a counting unit. Each unit of 10,000 is called "man."  This continues until 100,000,000 (ichioku).

10,000	ichiman 一万
100,000	juuman 十万
1,000,000	hyakuman 百万
10,000,000	senman 千万
100,000,000	ichioku 一億

"Man" and "oku" follow a regular rule except for 10,000 and 100,000,000. They are always "ichiman" and "ichioku" not just "man" and "oku." In most cases, the Japanese use the Arabic (Western) numbers when they write horizontally.

Let's look at how to say these numbers.

45	yonjuu go
132	hyaku sanjuu ni
3,687	sanzen roppyaku hachijuu nana
94,256	kyuuman yonsen nihyaku gojuu roku
285,719	nijuuhachiman gosen nanahyaku juu kyu
