Boøwy (pron: bóui) was a Japanese rock group consisting of Kyosuke Himuro (vocals), Tomoyasu Hotei (guitar), Tsunematsu Matsui (bass) and Makoto Takahashi (drums). They were a rock band that reached legendary status in Japan during the 1980s. Their style of play varied from punk to pop rock and they had fans of all ages. The 1990s band movement was credited to Boøwy as they popularized the formation of musical groups, which caused musical instrument sales to hit an all-time high during the 90s and the record companies signed and debuted 80 bands during the 90s in hopes of finding a new Boøwy.
The band gathered popularity, an eventually Boøwy became Japan's #1 rock band. They held a concert called Case of Boøwy in the Yokohama Cultural Gymnasium, in Kanagawa and in Kobe, Hyogo on July 31 and August 7, 1987, where they played most of their songs from their debut to the present for four hours straight. That same year they announced their breakup at a concert at Shibuya Kōkaidō on December 24. There are many rumors concerning the breakup, but the most popular is the rift between Hotei and Himuro. An indication of the band's stature at the time, is that at their farewell gigs (Last Gigs); two nights at the newly opened Tokyo Dome on April 4 and 5, 1988; they sold out all 95,000 tickets in ten minutes.
