YouTubers and Virtual YouTubers need legal advisors who are familiar with channel management and contract execution.


In Japan, YouTubers and VTubers generally sign a management contract with an agency to carry out their activities, while in some cases, they sign a contract with a company and engage in advertising activities.
Traditionally, management contracts between entertainers and entertainment agencies, as well as advertising contracts between entertainers and companies were used in the Japanese enterntainment industry. However, YouTubers and VTubers are slightly different from traditional entertainers because of YouTube’s terms and conditions.
A lawyer with knowledge and experience in Japanese contracts related to YouTubers can help you smoothly conclude a contract with the essential points. Our Japanese legal experts are well-versed in the unique aspects of the Japanese market and online video platforms.

Creating and Publishing Videos

When creating and publishing YouTube videos, it is essential to possess legal knowledge in various areas, such as copyrights for the music and objects appearing in the video, portrait/privacy rights, and advertising regulations that may be problematic when introducing cosmetics and health foods in Japan. Lack of legal knowledge in these areas can lead to the risk of having your videos deleted or, in the worst case, having your account banned in Japan.
