The song is included on the band’s 10th album. Following the album’s release announcement, Masayuki Nakano, the bassist and programmer of the duo, noted it would be Boom Boom Satellites’ final song due to Kawashima’s fourth brain tumor relapse. He detailed that the singer suffered from partial paralysis and would spend the last of his days peacefully with his family.
Boom Boom Satellites’ official website and Facebook page announced Kawashima’s passing Tuesday morning. Nakano commented, translated into English:
“At 5:12am on October 9th, BOOM BOOM
