There are some interesting legacies to the War that relate to fishing and boat building here in Okinawa. Before I arrived Shimojo san had roughed out a bailer for our boat. He used Okinawan pine and we are letting it dry before doing the final carving.
By far one of the most interesting uses of salvaged materials is the "tankobune" (tank boat) which were made from US Air Force aluminum drop fuel tanks, which must have rained down on Okinawa in the thousands. In addition to being used as water tanks (islanders collect rainwater from their roofs), fishermen were soon cutting them in half and making boats out of them. Here's one in the local museum.
Shimojo san told me that in his machine shop he was the first person to put an engine in a tankobune. He installed small, one cylinder gasoline engines in them. I asked how long these boats were used here and was told that they were common up until about twenty or thirty years ago, but tonight a visitor to my guest house insisted that he knew someone locally who used a tankobune until just a year or so ago. I couldn't help but ask if I could meet this person and see his boat, and tonight I got my chance.
