I get a kick out of the Japanese naming conventions for their ships. They had a destroyer named the
Floral Fragrance and one of their aircraft carriers that fought at Midway was named the
Increased Joy. The other Japanese carriers at Midway were the
Flying Dragon,
Green Dragon and
Red Castle.
Incidentally, Yamato was named for a Japanese province.
IJN Fleet carriers were named after the major islands in the Japanese archipelago.
All, Here is a great website that documents the IJN:
