Nan-J (なんJ) is short for Nandemo Jikkyō Jupiter (なんでも実況J(ジュピター)), one of the boards of 5channel (formerly known as 2channel), a Japanese BBS website.

Anons of the board are portrayed as strange-looking humanoid creatures named Yakiu no Oniichan (やきうのお兄ちゃん, "Big-Bro of Basebaww"). They like baseball and have a legend that they destroyed the natives (原住民 Genjuumin) who originally existed when they settled in the board in 2009.

In contrast to other Japanese web communities where Standard Japanese is chiefly spoken, Mōko-ben (猛虎弁, "Fierce Tiger Dialect"), a peculiar wording style based on Kansai dialect, is deemed standard in Nan-J and its derivatives or culturally-influenced communities. This originated when folks of the board played Hanshin Tigers fans sarcastically.
