Thank you all for your responses.

My parents are Japanese (born in Japan) but are naturalized Canadians. I was born in Canada.

My wife is a Japanese National.

I guess I can go at this from two different ways. Through my spouse or through my parents heritage.

I realize Japan does not recognize dual citizenship and since my parents immigrated to Canada and lost their Japanese citizenship. They no longer have their Japanese passports. Does this have any impact on my status? All my extended family are Japanese and all currently live in Japan.
