I'm curious, do you know why he was sent to an internment camp. From what I've read very few Japanese from Hawaii were sent to camps because that would've caused a major blow to the Hawaian economy. I've been fortunate enough to have met some veterans of the 442nd and also Japanese Americans who became translators for the US Army in WWII. At Fort Snelling in MN, the langauge school for training them was set up and several Japanese who were interred volunteered to become translators. A few of them ended up settling here after the war including a friend of mine's dad who ended up working at 3M, raised a family and got Judo going in Minnesota.
As far as I can tell, he ran a general store on Kauai that was very successful. He was appointed (unwillingly, I believe) to a Japanese consulate position, where pretty much his only duty was helping Japanese immigrants get their bearings and get integrated into Hawaii culture. He also set up a lending society for Japanese-Americans, many of whom couldn't get a loan from a regular bank. I suppose the government believed that even though he was in his 60s, he could conceivably rally all these Japanese and take over Kauai; ignoring the fact that his wife, and his 7 children were all born Americans...
