That's encouraging. The problem is that I have seen and heard about too many reports concerning Japanese people with American nationality who had their lives made difficult by Japanese officials - there's been a bit of a clampdown lately. There's at least one other regular poster on this forum who has also heard about similar instances.
One only needs money and time and perseverance to acquire British citizenship. I have no idea if it is even possible to regain Japanese nationality. Even if not many instances of denaturalisation occur doesn't mean that it can't happen. The stakes are too high to be leaving your future to the whims of bureaucrats and politicians.
Japanese bureaucracy is often described as 'paternalistic'. Worth reminding ourselves that the three greatest fears in this culture are: fire, earthquake, father.
