Kaoru Mitsumune

BIOGRAPHY

Kaoru Mitsumune (Japanese: 光宗薫; born April 26, 1993) is a Japanese actor, model, and illustrator signed to Ito Company. She plays Katagiri Asuna in the 2026 MBS boys’ love drama The Boy and I Who Will Break Up in 100 Days.

Born in Ehime Prefecture and raised in Osaka, she won the Grand Prix at the 2011 Kobe Collection, which led her to join AKB48’s 13th generation over the Osaka-based NMB48. She was introduced on the group’s theater stage on December 8, 2011, but announced her withdrawal on October 24, 2012, leaving after a brief roughly ten-month tenure.

She built an acting career after leaving the group, starring in the film Joshi Camera (2012) and appearing in the drama ATARU (2012) and its film sequel Gekijoban ATARU (2013), as well as the NHK asadora Mare (2015). She is also known as a visual artist, having reached “Meijin 10-dan” rank in watercolor painting on the TV art-competition segment Prevat!!. She joined Ito Company in January 2025.

BLGLFlix editorial view

She won a modelling competition, was placed into a group with dozens of members, and came out the other side as an actor and an illustrator.

Kaoru Mitsumune (光宗薫), born 26 April 1993 in Ehime and raised in Osaka, took the Grand Prix at the 2011 Kobe Collection and joined AKB48’s thirteenth generation. She is signed to Ito Company, and in 2026 she takes the part of Katagiri Asuna in the MBS adaptation The Boy and I Who Will Break Up in 100 Days.

Large Japanese idol groups work as a filter rather than a destination. Dozens of members enter, a handful get the promotion, and everybody eventually leaves. What matters afterwards is what each person built while inside: a following, a skill, a name people recognise. She left with all three and a second profession as an illustrator on top.

That is a fundamentally different shape of career from the Thai one this catalogue mostly documents, where a company signs an individual and manages them alone from the start. The group route produces people who arrived through competition, not selection.

Her birthplace is recorded here as Ehime with the Osaka upbringing noted, because one structured source lists Osaka instead. Where sources disagree we record both rather than quietly choosing.
