Thanks for researching all this information! I didn’t know there were so many Japanese Americans in Hawaii. I guess that does make U of Hawaii a good option. It seemed kind of far away but I’ll take a closer look.
I looked at U of SF and they said they take advantage of being near a Japanese American community and the Asian museum in the city so that looked good to me. They even said that their students could use the Asian libraries at Berkeley. I’m not sure how far away that is though.
