SIRUP brought the curtain down on the "OWARI DIARY" concert series with "SIRUP HALL TOUR 2026 'P.S.'"—a two-city finale that delivered on fan expectations and then some.

The Tokyo show on May 23 at LINE CUBE SHIBUYA and Osaka performance on May 24 at NHK Osaka Hall both sold out, with the singer framing these events as a postscript to the touring cycle that followed the September 2025 release of OWARI DIARY, an album described as a diary of real-life experiences.

The standout moment came when SIRUP invited Ayumu Imazu as a special guest in Tokyo. The two performed "UNDERCOVER feat. Ayumu Imazu" live for the first time, sending the venue into overdrive. After the performance, Imazu praised the crowd and energy before exiting, while SIRUP celebrated the long-awaited collaboration happening at last.

The Tokyo setlist was carefully constructed as a journey through different environments—opening with a streetscape and the "NO WAR" flag, transitioning to a living room setting, then shifting into a club atmosphere with heavy bass and flashy lighting during "OUR HEAVEN feat. Daichi Yamamoto." Throughout, SIRUP performed with dancers and a full band featuring horn and string sections, creating what felt like a complete artistic statement rather than a typical concert.

Notable performances included "LOOP," sung in harmony with the audience, and unreleased track "TIRED," which SIRUP used to discuss the difficulty of living authentically in an uncertain world. The artist closed with recent single "Not AI" before returning for an encore.

SIRUP, an R&B and neo-soul-influenced singer-songwriter known for international collaborations, continues to expand beyond borders—the artist's music has been nominated for Taiwan's Golden Melody Awards and has attracted recognition across Asia.

Fans can relive the Tokyo performance through U-NEXT, which will stream the show from July 25 through August 8. SIRUP also announced a vinyl release of OWARI DIARY, giving fans another format to experience the album.
