Here's what I understand of Japanese history. I don't know that much but here goes...
-The Japanese started out as the descendants of the Yayoi and Jomon peoples that migrated from mainland Asia.
-Originally lot's of infighting between the various clans however despite the infighting the various clans saw themselves as "Japanese" and distinguished themselves culturally in contrast to the Chinese, Mongols etc as opposed to each other.
-At some stage Japan was invaded by the Mongols but not entirely sure when. Bad weather was a factor in repelling the mongols both times.
-Ieyasu Tokugawa finally united Japan in the 17th century (I don't know how... did he conquer it all by force?)
-Japan invaded Okinawa (I think that happened after unification)
-Although the Japanese had been in contact with Europeans, it was limited and they preferred to be isolated. However sometime in the 19th century Japan began the move to modernisation and began to open up.
-Although isolated for a long time, much of their culture has a Chinese influence.
-Fought a war with Russia in the Early 20th century. Japan won that war.
-Signed a pact with Nazi Germany and Fascist Italy and invaded China, Korea and much of East Asia
-Attacked the United States of America bringing the United States into World War 2
-Surrendered and occupied by the United States in 1945.
-Rebuilt their economy to become the 2nd biggest economy in the world to this day.
Yup that's pretty much all I know... Correct me if I'm wrong
