As announced on the official website of the band BOOM BOOM SATELLITES, the singer and guitarist Michiyuki Kawashima died last Sunday, October 9th at 5:12 a.m. The singer suffered from partial paralysis as a result of a brain tumor that relapsed for the fourth time last August. The band had canceled their concerts in Osaka and Tokyo last November due to the deterioration of his condition.

The band's staff is preparing a farewell event for the fans and more details will be announced at a later date. Bassist Masayuki Nakano and Kawashima's long-time friend wrote the following message on their official page on Facebook:

“At 5:12am on October 9th, BOOM BOOM SATELLITES's vocalist Michiyuki Kawashima set off on the next stage of his journey.
