Ayaka has released a new single titled 'OK! GO!' as the official theme song for TBS's long-running information variety program 'King's Brunch.' The track became available for digital distribution on May 6, 2026.

The song carries an intentionally positive message designed to uplift listeners. According to the announcement, 'OK! GO!' aims to brighten Saturday mornings with encouraging energy that pushes people forward.

The track will receive its full-size radio debut on FM802's 'on-air with TACTY IN THE MORNING' program on April 20, airing around 9:00 AM.

This release arrives at a significant moment for Ayaka. The Osaka-born singer-songwriter is currently celebrating her 20th anniversary since debuting in February 2006 with 'I believe.' Her debut album 'First Message,' released that same year, shipped over 1.4 million copies, establishing her as a major force in the Japanese music industry. She followed this with a best-of collection that achieved multi-platinum status in 2009.

Throughout her career, Ayaka has maintained a distinctive approach to live performance, alternating between intimate acoustic setups featuring just guitar, piano, and vocals, and full band arrangements. She's also expanded into dinner concerts and symphonic performances. Her extensive catalog has become culturally embedded, with many of her songs regularly covered across generations.

Most recently, Ayaka released her eighth studio album 'Wonder!' in September 2025, featuring 11 diverse tracks. As she moves into her third decade as a recording artist, projects like the 'King's Brunch' theme song demonstrate her continued relevance in Japanese entertainment and her ability to craft music that resonates with mainstream audiences.
