RIIZE Sets Sunburst Countdown With MV Teaser

RIIZE has opened the runway for its next Japanese release with the official teaser for "Sunburst," a 33-second MV preview uploaded through SMTOWN. According to SMTOWN's official YouTube channel, "Sunburst" is the group's third Japan single and is scheduled for release on August 26 at 0 a.m. KST and JST, giving BRIIZE a short but highly focused countdown window before the full track arrives.

The teaser lands at a useful moment for the group's global narrative. Korean entertainment outlets including TenAsia and Herald Muse reported that RIIZE's "Do your dance" entered the U.S. Mediabase Top 40 radio chart, marking the group's first appearance on that format and extending the conversation around its reach outside Korea and Japan. That context makes "Sunburst" more than a regional single. It arrives as RIIZE is being discussed as a group with widening international touchpoints, from Japanese promotions to North American radio exposure.

A Japan single built for a global fandom

The official description keeps the essentials simple: RIIZE, "Sunburst," third Japan single, August 26 release, and pre-order/save links. That direct structure is typical of a teaser designed to move fans from curiosity to action. The video does not need to reveal the full song. Its purpose is to establish the title, mood and release time clearly enough that fans can organize around the drop across YouTube, streaming platforms, Weverse and social channels.

For RIIZE, Japan is not a side lane. It is one of the group's most important growth markets, and a third Japan single suggests a steady rhythm rather than a one-off overseas push. The use of both KST and JST in the official release timing also speaks to how K-pop schedules now operate across closely linked fan bases. Korean, Japanese and international fans can coordinate the same midnight moment without confusion, which helps amplify early views and searches.

"Sunburst" itself is a title with strong visual symbolism, marking both the release energy and a progression from the group's earlier singles. As RIIZE continues to build its presence across regions and formats, this teaser shows a group moving with strategic intent rather than experimental reach.
