NIJISANJI (main branch)

''This article is about the main branch of NIJISANJI Project based in Japan. For a general overview comprising all the branches, see NIJISANJI.''



NIJISANJI (にじさんじ) is the main branch of the NIJISANJI Project. Prior to April 2022, it was exclusively comprised of Japanese-speaking Livers catering to a Japanese audience, so it was sometimes unofficially referred to as "NIJISANJI JP" to distinguish it from overseas branches. The Indonesian and Korean branches merged with the main branch on 15 April 2022.

Kuzuha, a Japanese member of the branch, is the most-subscribed male VTuber worldwide with over 1.4 million subscribers; and Hyakumantenbara Salome, also a Japanese member of the main branch, is the current world record holder for being the fastest VTuber to reach 1 million subscribers in just under 14 days.

Trivia

 * NIJISANJI's app has a mascot called Yugamin. Livers can stream as Yugamin instead of their usual forms as Yugamin has a Live2D model. Yugamin was designed by ほーじろ, who also designed Shibuya Hajime, Kenmochi Toya, Fushimi Gaku, Sister Cleaire, Amemori Sayo, Todoroki Kyoko, and Yumeoi Kakeru.
 * Whenever someone who isn't a Liver appears in a 3D stream, their avatar is that of a kuroko (黒衣, black-clad), a stagehand in traditional Japanese theater wearing black clothes that cover the entire body. The kuroko are usually ANYCOLOR staff.
 * There has been multiple instances where a model was left unused, one notable example being that of "Eudrick" who was revealed all the way back during NIJISANJI's conception but has since become a running joke among members.
