Nippon-shiki (日本式), or "Japan-style," is a system for rendering the Japanese language in the Latin alphabet (romaji). It conforms strictly to the kana writing system, and is easier for Japanese natives to interpret than the more anglicized Hepburn system: however, most foreigners find it to be unintuitive to pronounce.

Some examples:

Mount FujiふじさんFujisanHuzisan
kana spellingかなづかいkanazukaikanadukai

The system was invented by physicist Akitsu Tanakadate in 1885. Since then, the Kunrei-shiki has been developed as a compromise between Nippon and Hepburn. The JSL system, which is targeted at foreign students of Japanese, is also based on Nippon-shiki.
