Today we got Satoshi's Japanese passport. About 2 weeks ago we got his American passport. In America it is ok to be a dual citizen, but in Japan only children can be dual citizens. Satoshi has to decide which passport to keep by his 22nd birthday and give up the other one. That is a long time from now, so I hope the law will change before then.
We now have 6 passports for 4 people!
