RIIZE drops teaser for third Japan single 'Sunburst,' out August 26

RIIZE has put out the music video teaser for "Sunburst," the group's third single made specifically for the Japanese market. SMTOWN posted the clip to YouTube and SM Entertainment shared it again on Instagram, both on August 23, 2026, confirming the single lands August 26 at midnight in both Korea and Japan.

For listeners tracking RIIZE's Japan run, this is the marker that tells you the wait is almost over. A teaser drop three days ahead of release is the standard rhythm K-pop labels use before a single goes live, and it usually signals that the full video and audio are locked and ready.

What's notable here is that "Sunburst" is built for Japan specifically, not a repackaged Korean track. That distinction matters for a group still expanding its footprint outside Korea, since a dedicated local single usually comes with its own promotional push in that market, separate from whatever the group has planned back home.

Pre-orders are already open through RIIZE.lnk.to/Sunburst, so anyone who wants a copy of the single doesn't have to wait for release day to lock it in. Once August 26 hits at 0:00 KST/JST, the full music video should follow the same channels — SMTOWN's YouTube and RIIZE's own social accounts — where the teaser first appeared this week.
