Source-derived summary

Sumika (stylized as sumika) is a Japanese rock band from Kawasaki, Kanagawa. The band formed as an indie rock band in 2013, before being signed to a major label in 2018. The band is also known as Sumika [camp session] during live performances, which are known for including performances by non-musicians such as filmmakers, photographers, painters, sculptors, architects, potters, and poets. The band's music has also been featured in the anime series Wotakoi: Love is Hard for Otaku, Mix: Meisei Story, Pretty Boy Detective Club, Delicious in Dungeon, and the anime films I Want to Eat Your Pancreas and My Hero Academia: Heroes Rising.

The band is affiliated with Sony Music Entertainment Japan.

History

Sumika was formed in Kawasaki, Kanagawa, in May 2013. The group's name is derived from the Japanese word sumika (すみか, residence), and refers to the desire of its members to consider the band as their "house" or their "room". The original members were Kenta Kataoka, Junnosuke Kuroda, and Tomoyuki Arai. Takayuki Ogawa, who had previously performed with the group as a guest member, joined the group full-time in 2015.

Sumika debuted in 2013 with the release of their first mini-album Shinsekai Orichalcum (新世界オリハルコン) in October of that year.

Editorial analysis

Why this record matters

The phrase “japanese musical group; rock band” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

Evidence profile

Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Sep 4, 2026. The linked authority identifier is Q24902573. 1 of 2 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank. The first chronological checks are 2013, 2018 and 2015.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it
