Most readers will know that Japan allows only one nationality. However, for the longest time, so long as a person was registered as a Japanese citizen first, whether or not you had gained a second nationality was politely ignored by the authorities. You just had to make sure that you didn't make it too obvious that you held a separate nationality. But now it appears that things are changing and the Justice Ministry seems to be conducting checks on Japanese citizens living overseas to make sure that they do not have dual nationality. For a sense of the situation, here is an extract from one reader's letter:
"...I recently decided, after many years as a green card holder, to apply for US citizenship. This was partly triggered by the increasing tension of the US immigration process, which has understandably changed in attitude since 9/11. The tipping point for me was when a lawyer in Japan advised me that although dual citizenships are technically forbidden in Japan, it is a law that is not enforced. Before I could complete my application process, however, I was told by another person that things in fact had changed. I confirmed this with the authorities. It seems that if you are Japanese and you renew your Japanese passport at your local US consulate, when you go to pick it up you are asked to show your green card or other residency documentation which allows you to be in the US. If you cannot produce this documentation, and you wouldn't be able to if you held a US passport, they won't hand over your new Japanese passport. Apparently this is how they are now catching dual citizens living abroad. To avoid this, I could renew my passport in Tokyo, but if I do, I have to show them my juminhyo [Ed: personal register of your residency matters]. That means I have to re-establish residency and live back in Japan for a few months -- which of course is difficult to do when one has a career to fulfill"...more...
