Base Ball Bear is a rock/pop band from Tōkyō, Japan that formally began in 2002, although the members assembled in the autumn of 2001. Base Ball Bear was originally called PLANET and was formed for a one-time performance at a high school culture festival, but they decided to continue playing due to how well they were received at the festival and how much fun they were having. The band made its major debut in early 2006. Their style influences include Japanese bands NUMBER GIRL and SUPERCAR, and British rock/pop bands such as Oasis. Base Ball Bear is recognized for the 'nostalgic' feel of Koide's lyrics, often about teenage life and memories. They are also known for their contributions to the soundtrack and cast of the movie Linda Linda Linda and to anime fans for performing the opening theme to the series Ōkiku Furikabutte.
The band's former name, PLANET, most likely came from a SUPERCAR song of the same name. Their current name also derives partially from a song name. Koide thought of Japanese singer Chocolat's song "BASE BALL and Elvis Presley", and suggested the name "BASE BALL". Yuasa thought it would be better if they added one more word to it, and the rest of the band agreed. They eventually settled on the word "bear".
