maeda Iwo jima. the maeda family were governors of Iwa Jima (not iwo jima) for 5 generations until the 1950's. do you have any information on maeda of Iwa jima?
Dude, I lived in Japan for a few years and I didn't even know there was an Iwa Jima Prefecture. Whereabouts is it? I expect if you write the prefecture offices and ask for them to help you with the records, they could get everything you need.
