175R (１７５Ｒ, Inago Raidā, "Inago Rider") is a Japanese ska punk band from Kitakyūshū, Fukuoka Prefecture.
Debuting in 2001, 175R has released seven singles, seven albums and four DVDs. The band's members include Shogo on Vocals, Kazya on guitar, Isakick on bass and Yoshiaki on drums. The band shared their second single with the band Shaka Labbits. The name 175R means "Inago Rider," which is derived from the goroawase of "175" plus "R" for "rider." Inago (蝗) means grasshopper in Japanese, as a reference to the popular Kamen Rider Series of tokusatsu television programs. In 2007, the group's single "Yume de Aeta Nara..." was featured as the ending theme for the film Kamen Rider Den-O: I'm Born!.
Another one of their songs, Melody, was used featured in a music-related video game for the Nintendo DS called Osu! Tatakae! Ouendan. Unlike the other songs included in the game, Ouendan made use of an actual (albeit edited) 175R recording, instead of a cover version.
