Music idol Momona Kozakura makes porn debut as Haruka Tachibana

The former momograci music idol Momona Kozakura (小桜ももな) is making her porn debut as Haruka Tachibana (橘春花) in a new release from IDEAPOCKET’s First Impression series of adult videos.

Releasing November 10, Old School Idol Who Dedicated Her Youth to Live Performances and Gravure Now Super-Nervously Makes Her Solo Debut in Porn is, as the title very clearly states, nominally about a 24-year-old’s progression from music idol to adult performer after six years as a music idol. The idol is presented as a “pure” young lady whose hobbies are playing the piano, doing tea ceremony, and dance.

Overtly self-referential, if not outright autobiographical, the 154-minute AV (IDPC-032) is one of the most hotly anticipated releases of the month. “A New Idol Is Reborn,” as the AV tagline somewhat confusingly says. The marketing is parodying the language of music idol culture when members make career-changing “resolutions.”

Immediately after retiring as an idol, she makes her debut in the adult video industry.

Former entertainer Haruka Tachibana makes her solo debut.

A true hybrid talent, combining the worlds of authentic idol and professional glamour model.

Her resolute declaration: “I am leaving my idol days behind.”

It’s embarrassing . . . and I’m anxious, too . . . but—

It’s okay to stumble . . . It’s okay to fall . . . but I want to keep running!

I want to continue being someone special to all of you!!!

After six years in the entertainment industry—

She sheds the persona of the “innocent, pure-hearted” idol—

This is the first, and greatest, fan service from AV actress Haruka Tachibana!

Onward to a brand-new stage.

The content of the porn itself looks pretty conventional, even tame, but Kozakura/Tachibana’s girl-next-door, pure face and slim body elevate things to another level.

The Aichi-born Kozakura, who has also performed briefly in early 2026 as Reika Asakura with the group My Starry Diary, was a member of momograci (aka Momoiro Revolution) in the first half of 2025. The six-member group burns through idols quite quickly and has also changed its name several times since it was founded in 2016.

This is what she looked like during her momograci days, just a year or so ago and yet she is so different.
