Ninjutsu is just another form of martial arts taught at the regular community centre here in Singapore. It's not what you imagine though, nothing to do with chakra, kunai, or even shurikens. Just basic moves and such, but they have a black gi which looks pretty cool. All in all, it's just another form of money making for the people conducting the course. But I understand that there is still at least one living ninja in Japan, but even his clan is non existing now and he basically earns a living by being the last ninja and getting paid to be on documentaries.
