Freedom of expression is guaranteed, censorship is according to the constitution, strictly forbidden in Japan like other modern free countries. However, some censorship is , in reality, covertly ongoing in many fields. They strongly have chilling effects.
One example is, movie directors. Most of them are wittingly or not wittingly, internalized this code the creativities are spoiled. As we instance, can see movie, mentioning the ‘cult’ Oumu Shinrikyo is taboo. And also, most publishers are reluctant to release books on this issue said the business representative when I had asked.
This conditions around the film and publishing world makes a sharp contrast to U.S. right now. To say,the Paul Thomas Anderson’s newest work ‘The Master'; which dealt with allegedly cult Scientology, controversial but very suggestive .
But we can find out a few exceptions who are challenging this canny code. Only one director who dealt with this topic is Tatusya Mori, documentary film director. and Shuutaro Oku, who had made USB which dealt with nuclear industry and its problem before 3.11 Fukushima crisis happend.
