In fact, moves to expand the role of Japan's self-defence forces in foreign peacekeeping operations have caused concern in some quarters.
"It is unknown territory," says political science professor Koichi Nakano. "Maybe the government will try to normalise occasional death in the self-defence force and perhaps even try to glorify the exercise of weapons?"
According to Iain Overton, the "almost taboo level of rejection" of guns in Japan means that the country is "edging towards a perfect place" - though he points out that Iceland also achieves a very low rate of gun crime, despite a much higher level of gun ownership.
Henrietta Moore of the Institute for Global Prosperity at University College London applauds the Japanese for not viewing gun ownership as "a civil liberty", and rejecting the idea of firearms as "something you use to defend your property against others".
But for Japanese gangsters the tight gun control laws are a problem. Yakuza gun crime has sharply declined in the last 15 years, but those who continue to carry firearms have to find ingenious ways of smuggling them into the country.
