Japan was a nation on Earth, just off the east coast of Asia. It is composed of four major islands, Hokkaido, Honshu, Kyushu, and Shikoku, and many smaller islands, with its capital in the city of Tokyo.
The primary language of Japan was Japanese. In 2377, Bart Faulwell discovered similarities between the written language of the Ardanan culture and Japanese (as well as Chinese and Andorii). (CoE eBook: Signs from Heaven)
