On October 22, there will be an examination for certification in the Koga-ryu school of ninjutsu. I am not making this up.
According to At Press, the certification test will be held at Zojo-ji, a Buddhist temple in Tokyo. The examination is thirty minutes long and covers your ninja knowledge of the Koga-ryu school.
Since the test is open to those in fifth grade and up, it probably isn’t that hard. A score above sixty is passing, and you can get another ten points based on your ninja outfit or ability to throw shuriken.
