Katsutoshi 'Kuso' Munechika, also known as Kusomiso and under various other names, was an underground Japanese noise/experimental musician, bass player, founder of Cosmo Baby label. In the mid-eighties, Katsutoshi was an intermittent member of the controversial noise collective The Gerogerigegege and had collaborated with its founder Juntaro Yamanouchi on many occasions. They recorded a few tracks together as Gero-Kuso for cassette compilation, released in 1994 by (later re-released on the '99 memorial tape).

In the liner notes to a '98 , Kuso is credited, alongside with Toshinori Fukuda on drums, as a vocalist on "75 Live Songs (1987)," a 31-min long track which is supposed to be a 'remastered' album. On the original Tokyo Anal Dynamite, recorded in Oct 1987, vocals were simply marked as —in Japanese, it literally means "he/she/they died," an equivalent of 'obiit' or a 'dagger' † symbol next to the deceased person's name. Fukuda, who wasn't really much known other than Dynamite Gero and didn't have any credited appearances after ~1988, could've already passed away by the T.A.D. CD was released in 1990. Unlike him, Munechika certainly continued playing and recording at least until the mid-nineties, which calls the credibility of either Tokyo Anal Dynamite's or Recollections Of Primary Masturbation's liner notes in question.

He had been in the hospital since Nov 2017 and died due to aspiration pneumonia on 12th May 2020, aged 51.
