When I went into the university, I saw two men hanging over a board written "原発即停止" (It means "Nuclear power plants' operation should be suspended right away.")
One of them approached me and delivered handout to me with saying "Let's stop operation of nunclear power plants.". I ignored his action because I was busy in preparing for a guest professor's visiting rather than because I'm not an anti nuclear power plant abtivist.
I'm afraid that they intend to brainwash college students.
