My list of Japanese museums is fairly limited at the moment, and, sadly, many of the best known maritime museums and collections have closed for budgetary reasons. Some may only be temporary closures, and hopefully they will open again someday.
Tokyo Museum of Maritime Science – While it has been closed since 2011, this is a large museum with a large collection of models of Japanese ships and watercraft, from early river boats to modern steel hull ships. The published reason is that it’s closed for renovation. But, I’ve heard that it’s partly a dispute between the owner of the museum and the city of Tokyo. The museum has an annex that is apparently open, and there are some maritime displays there, but the large model collection is not on display, though the models sometimes show up at temporary exhibits as needed.
Toba Seafolk Museum – This is a very nice museum located in Toba, which is in the Ise Prefecture, about 2 hours by express train south of Nagoya. The museum has a very large repository of 90 small boats. It is difficult to examine many of them because they are stacked together fairly closely, making it difficult to see all the details of most of the boats. Also, the lighting, as in most Japanese museums, is very dim, making photography difficult. However, the main exhibit areas are interesting and there is a lot of information to be had.
Ogi Folk Museum – This museum on Sado Island is the home of the most accessible and well preserved of the bezaisen replica ships, the Hakusanmaru. The ship is housed inside the museum building, where I believe the ship was originally built, and it takes up the bulk of the space. The ship is a Kitamaebune, which is a northern port coastal trade ship. A wooden stair case provides access aboard the ship, and you can freely walk around the deck, inside the main cabin, and down into the hold, giving you a first-hand look at the details of the ship’s construction. Nearby, there is a cutaway display showing a cross-section of the hull, a large cutaway model of the ship, and a tenmasen, a small boat that would be carried aboard the ship and used for shuttling cargo and crew to and from shore.
In separate buildings, the museum also has collections of artifacts, and one building houses fishing gear and some old wooden boats from the area.
Urayasu Museum – Located at the south end of Tokyo, not far from Disneyland, is a small museum dedicated to preserving a glimpse of the once thriving fishing village that existed here. The museum has a reproduction of a section of the fishing village as it looked in the 1950s. In the lower floor of the main museum building is a workshop, where you may meet one of the last Urayasu boatbuilders working on boats or models of them.
