Ancient times, we used to convey information by singing and dancing. It might have been the beginning of Theatre. In other words, it could have been a primitive theatre. Since there was no text, no photo, no video, the information that comes from people had shaped the culture.

However, not all information which was conveyed in that way cannot be positive. Rumors and Gossip sometimes generated demagogue and agitation.

Then, let’s consider "SNS" as a modern oral culture.

Nowadays, in Japan, many people are exposed to abuse and defamation on SNS, and it has been constantly increasing the number of young people who choose the way of "Suicide". The tool for expanding the world that connects humans created a narrow and abnormal world in which there is only "You" and "Not you (= enemy)".

It can be said as "Spread of unhappiness infection", and it is a new & large lesion of modern Japanese society.

The bad faith of people becomes a black Tsunami and it will be swallowing people and taking their lives.

It is not the blades or guns that kill them but the "Word".
