Kiko Mizuhara has made her solo artist debut with the digital single "Feelin' Wee," released on September 2 through Los Angeles-based record label Stones Throw.

Mizuhara previously teamed up with her sister Yuka Mizuhara and producer John Carroll Kirby in 2025 for a cover of Haruomi Hosono's "Fuku wa Uchi Oni wa Soto." After Kirby encouraged her to try writing lyrics, Mizuhara began working on original music.

Mizuhara shared, "I think people are like diamonds. Depending on the angle you look from, you can see completely different sides. I have many different sides to myself as well, so expressing them through music has been really fun and freeing." She added, "'Feelin' Wee' is a song that came from letting my imagination run free. It's funky, a little mysterious, and playful."

The music video for "Feelin' Wee" has also been released on YouTube. Produced by Kirby and directed by Luke Casey, the video features Mizuhara singing and dancing in a dreamlike setting.
