Old Photos of Japan is a fine blog aptly described by its title. A search for "boats" pulls up only a few hits, but they're quite interesting. I won't bother paraphrasing the content; just follow the links to the full articles.
The Ainu are the native people of Japan's northern island of Hokkaido. This article mentions their dugouts and describes their lashed canoes and sailboats. (Photo from the 1920s.)
Ainu fishermen in dugouts, with very specialized fish spears (photo from 1900s). Lots of detail here.
Thanks to Heather Hernandez, technical services librarian at San Francisco Maritime National Historic Park and blogger for Maritime Compass, for passing along this fine resource. Thanks also to Old Photos of Japan.
