Arashi is a popular Japanese idol group consisting of five members formed under the Johnny's Entertainment talent agency. The members are Ohno Satoshi, Sakurai Sho, Aiba Masaki, Ninomiya Kazunari and Matsumoto Jun. The group was officially formed on September 15, 1999, in Honolulu, Hawaii, and made their debut CD on November 3, 1999. The group was initially signed to Pony Canyon and released one studio album and six singles—beginning with their 1999 eponymous debut single before moving to the Johnny's subsidiary label J Storm in 2001, which was initially set up for their succeeding releases. While their debut single debuted atop the Oricon weekly chart selling a little over half a million copies, the group subsequently faced slowly declining sales.
