Last year, a man died at a famous naked festival.
You can find other dangerous festivals which kill people in Japan. And some people are not corporate-loyal worriers, but live to join their festivals. Of course, the people did not participate in the festivals to be killed, but I don't know if they were unhappy or not.
Tokyo police has recently announced that they would restrict the famous Tokyo festival, Sanja Fes., not to climb up the small shrines. This must cause controversy among participants.
Matsuri or festival is not always here, so some women are excited to use the bathroom.
A fast food shop nearby has an unisex bathroom, and I am wondering if you would use it when women are waiting.
