Michiyuki Kawashima, who made up one half of Boom Boom Satellites on vocals and guitar, passed away on Sunday, October 9th. He’d been living with partial paralysis after a fourth brain tumour relapse. The band’s official Facebook page said his death was caused by the tumour, and that while his wake and funeral will be private, a farewell event will be held for fans at a later date. Kawashima was 47.

The duo’s bassist, Masayuki Nakano, wrote his own official statement on Facebook:

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

I imagine he is soaring around the world, finally freed from the restrictions of his body. His passing is not a tragedy, but the achievement of a lifetime goal and a happy ending. The love of our many fans supported Michiyuki Kawashima and BOOM BOOM SATELLITES on their journey, and we are truly happy and lucky because of you.

On behalf of Michiyuki Kawashima, I would like to thank all our fans and colleagues again.

Thank you for supporting us up until now. Live your lives with passion and energy and keep the music we made, the time we spent together, and the memories we shared close to you.

One more thing, we are BOOM BOOM SATELLITES!!

This summer, their Kiznaiver OP ‘Lay Your Hands On Me’ became their final release. They disbanded after the song’s EP because of Kawashima’s worsening health. At the time, Nakano said “Michiyuki Kawashima has now closed his life as a musician and is spending his days living peacefully with his family”. Before, they had not only contributed music to other prominent anime like Appleseed and Mobile Suit Gundam UC, but also to Christopher Nolan’s film The Dark Knight.

We wish hope to Michiyuki Kawashima’s family and loved ones. His music will live on with all of us, so may he rest in peace.

He died early, and it’s always sad to see someone pass away so soon because of diseases. I hope he didn’t suffer a lot!


Unbelievable, only 47 years of age. That is truly tragic 🙁

It really is 😢 And to think he had to get through four relapses, all that hope and agony. Nakano’s right, at least now he’s free from it all.


Yes, sometimes you wonder why things like this happen. But you are right, he is from it now. But these are always sad things to read 🙁


Wow so crazy and sad
