He was 29 years old. The funeral was held among family and close friends. A farewell ceremony for the people who supported them will be also held at a later time.

Aoyama joined as the drummer of nano.RIPE in March 2013. He has since then released five singles, three studio albums, and performed at five live tours alongside the other members Kimiko, Jun Sasaki, and Nobuyuki Abe. Some titles include "Gekka" and "Star Chart," which were used as the ending theme songs for Hataraku Maou-sama!, "Nanairo Biyori" and "Kodama Kotodama" used in the Non Non Biyori series, and the last title "Snow Drop" for the second season of Shokugeki no Souma.

The drummer left the band in December of 2016 with former bassist Nobuyuki Abe. According to Sponichi Annex, he is the son of the well-known drummer Jun Aoyama, who died from pulmonary embolism in 2013.
