Are Few Japanese the Users of Blogger?

I feel that few Japanese use this Blogger. I see many blogs on this Blogger expressed in not Japanese but English. Even Japanese bloggers use English. When I started to blog, I planned to write Japanese essays. Because many readers may read only English, I can't do without writing English in this Blogger.

Hey, Jap! Use the Blogger and write Japanese. You did away with your nationality, didn't you? You must write in Japanese if you are a Japanese and proud of being a Japanese.
