Frequently Asked Questions

  • Q1 : Why does MTCM have no option to completely prohibit for commercial purposes?
    • A1 : MTCM basically provides materials used for game creation.
      *It is not limited to game production.

      In recent years, cases of it are “for commercial purposes” that are difficult to judge are increasing. It is necessary to clarify the purpose of commercial, but we have determined that it is difficult to classify it, and we have not adopted it for MTCM.
      In order to confirm this strictly, we think that it is necessary to issue permission each time to the user or create a contract that is supervised by a legal expert.

      Here are some examples that are difficult to judge:
      • Advertising revenue at sites that distribute materials.
      • Advertising revenue from uploading work of playing video game to YouTube using materials.
      • Income from paid distribution / Sales of game creator.
  • Q2 : Why does MTCM have no option to prohibit the use of age-restricted works?
    • A2 : In most cases, it is the game creator who determines the age-restricted of the game. Even if the material provider feels that this is an adult designation, it is impossible to make a legal decision in Japan. Judging that the effect is not expected, we have not adopted it for MTCM.


      Here are some examples that have no legal basis:

      • Age-restrictions on movie appreciation are set by the Eirin, the Film Classification and Rating Committee (Configured within the film industry) and are not regulated by law.
      • There is no legal age-restricted for browsing adult sites. Confirmation indications that are over 18 years old is the premise of the management site, "being considerate about the person under age"
