Jipangu

A modern Japan Maritime Self-Defense Force vessel, the JDS Mirai (meaning "future"), is en route to participate in a military exercise with the US Navy near Hawaii. In the vicinity of Midway Island it encounters a strange meteorological phenomenon that throws it back through time to the eve of the Battle of Midway of World War II. After rescuing an Imperial Japanese Navy commissioned officer, Takumi Kusaka, the "Mirai" and its crew go on to affect the course of history itself.
