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 is 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.
Hyakumantenbara Salome, a Japanese member of the main branch, was the world record holder for being the fastest VTuber to reach 1 million subscribers in just under 14 days.
