I was snooping around on the Internet, when I came across videos and articles about actual ninjutsu schools, like the Bunjinkan of Masaaki Hatsumi. I did some searches about what the shcool had to offer, and I was pretty excited to try my hand one day. But, I also found ton of videos or forum posts, who made harsh critics about ninjutsu teacher on the internet, mocking them and showing that they were fraud. Now, I'm asking, are all the ninjutsu fraudulent like said in these videos or the reality is more shady? Thanks a lot for your answer and have a good day!
