P4C, a synth-pop music project led by artist Kinako Nishinakajima, has announced a major roster expansion. The collective, which operates regional teams across Japan, now features new talent joining both its Kanto and Kansai divisions.

The Kanto team welcomes five members: Kikuchiyo (vocals), ☆彡Ki (track operation and vocals), Uta (drums), Yanamoto Yana (keyboards), and Inuai Natsuki (guitar). The Kansai team adds Mzk (vocals) and Hitomi (trombone), with additional members expected to be announced during the Osaka show.

P4C launched in September 2025 as a collaborative project bringing together musicians and creative practitioners. The structure allows the collective to maintain active presence in both the Tokyo and Osaka music scenes through dedicated regional teams.

The expanded lineup will debut at two headline shows this summer. The Kanto team performs July 16 at BASEMENTBAR in Shimokitazawa, Tokyo, followed by the Kansai team's appearance July 28 at Umeda LIVE SPACE ODYSSEY in Osaka. A third show is scheduled for August 18 at club vijon in Kitahoribashi, Osaka.

New artist photography for the project was created by ☆彡Ki, reflecting the collective's emphasis on members contributing across multiple creative disciplines.

Nishinakajima has built an extensive creative career since beginning home recording in 2014. Her work spans solo releases, collaborative albums with producer Yasunao Yoshida, hip-hop units, and band projects. The P4C initiative continues her pattern of building inclusive creative communities that welcome musicians, visual artists, and other collaborators.

The project represents an evolving approach to contemporary Japanese synth-pop, emphasizing collective participation and regional musical communities. Fans interested in the new direction can follow P4C on Instagram and X for updates on the upcoming performances and potential future announcements.
