ASTRO’s Yoon Sanha is officially going on tour. Following the announcement of his second solo mini-album CHAMELEON, the singer will kick off his 2025 fan concert tour, PRISM: FROM Y TO A, starting this August.
On June 25, Fantagio dropped the PRISM: FROM Y TO A poster along with the schedule and ticketing details.
This will be Sanha’s first solo fan-con in about a year, following Dusk Till Dawn, which was held in Korea and Japan last year.
His new tour title is inspired by the range of colors refracted from a prism and the letters in his English name, Yoon Sanha. It symbolizes a journey that unveils every facet of his identity, from ‘Y’ to ‘A.’
To match the tour’s concept, the ASTRO member also released a new mood film — the INTERNAL version — alongside the announcement. In contrast to the bold, edgy vibe of the EXTERNAL version, the new clip highlights a softer, more introspective side of the singer.
From brooding close-ups to calm, emotional shots, the film reflects the layered charm Sanha promises to deliver in both his album and tour. His styling in the teaser, from cargo pants to biker-inspired looks, shows off the versatility fans have come to love — and expect more of in CHAMELEON.
Sanha Tour ‘PRISM: FROM Y TO A’ Schedule
The tour ‘PRISM: FROM Y TO A’ begins with two nights in Seoul in August before the singer heads overseas to meet fans in South America and Asia. According to the concert poster and mood film shared by his agency Fantagio on June 24, the confirmed stops include
- August 1-2, 2025 – Seoul (Blue Square)
- August 5, 2025 – São Paulo

- August 10, 2025 – Mexico City
- September 5-6, 2025 – Kobe

The phrase “and more” at the bottom of the poster hints that additional cities may be added soon.
Ticketing Details
Tickets for the Seoul concerts will be available through the online platform NOL Ticket. Fan club pre-sales will begin at 8 PM on July 1, followed by general ticket sales opening at 8 PM on July 3.
Meanwhile, Sanha’s new mini-album CHAMELEON drops on July 15, ahead of the tour’s opening in Seoul. He made his solo debut with the mini-album DUSK in August 2024 and is now making his first comeback after nearly a year.
