It is suspected that the USJ is dealing with a formative design company whose boss hid his son's horrible bullying case in conspiracy with some influential people. The Boss's name is Mazuka Kimura and his company's name is Mazuka 3D works.
In Shiga Pref Japan, Oct 2011, a boy leaped to death after a seriously bullying. One of the ringleader boys was Mazuka Kimura's son. The boys' parents including Mazuka Kimura and teachers and the school board hid such a horrible bullying case to protect themselves. Recently the facts happened to come out and now they are being flamed on Japanese internet BBSs.
