Dirk T - the ease of renewing your J passport at a Consulate overseas depends on which one you go to. The Consulate my children renewed their J passport at for many years, were quite aware there were many half kids who most likely had dual citizenship and even gave out information in English about how to renew a Japanese passport. They never asked about another nationality and we and other families like us never declared there was one. However I have heard of other J Consulates that are very strict and when dual kids go to renew a J passport over the age of 22 they ask to see the visa or PR sticker in their J passport. Not having this could indicate of course they have dual citizenship. Nowadays when our kids visit Japan they usually enter on their non J passport being scared of being held up at the airport with questions about dual citizenship however they still keep their J passport. I do believe dual citizenship will be recognised one day by Japan and tell them just keep their citizenship until this day comes.
