Please advise us in Japanese, not translated into English.
I would like to name the company that is easy to understand for people in overseas.
It would be nice to include the meaning that we are No.1 in Japan.

1. Top of Japan
2. Top in Japan

Which one is correct from the view of native speaker?
Both are translated into the same way in Japanese according to Yahoo transtlation and Google translation. So I am not sure which one is the correct.

If you have any other suggestion, please kindly let me know.
