RIIZE released its Japanese 3rd single “Sunburst,” unveiled the MV, started a JOYSOUND campaign, and held a showcase streamed on YouTube.

RIIZE released its Japanese 3rd single “Sunburst” today (the 26th). At midnight today, the release date, the music video for the title track “Sunburst” was unveiled, and furthermore, from 11 a.m., a collaboration campaign with JOYSOUND also started. In addition, this evening, a release commemorative showcase for the Japanese 3rd single “Sunburst” will be held. As previously announced, that event will be live-streamed on YouTube from 4:30 p.m. Today, the release date of the Japanese 3rd single “Sunburst” will be a day to enjoy in various forms: with the music video, karaoke, and live performance. “Sunburst” is a house-based summer tune that lets you feel the refreshing energy of a summer day. It is a song that compares the feeling of wanting to draw out the future together with the person you are spending this moment with to the “sunburst,” the light that shines in from the sky. In the music video, the dazzling and refreshing energy that the song has is depicted as a youthful moment spent together by the members. While the joy of being together in the present moment is shown throughout, such as their innocent laughter and the way they enjoy ordinary time, there also drifts a somewhat sad and nostalgic atmosphere that makes you feel that that time will not continue forever. Through their 모습 of remaining boyish while gradually approaching adulthood, it captured a fleeting, irreplaceable moment of youth that can never be returned to again. In a way that overlaps with the feeling embedded in the song—“I want to draw out the future beyond this with the person I am spending the present with”—the music video expresses in images the dazzling present and the time that continues beyond it. Furthermore, in commemoration of the release of the Japanese 3rd single “Sunburst,” the “RIIZE x JOYSOUND collaboration campaign” started today from 11 a.m. During the campaign period, if you sing “Sunburst” at karaoke stores that have the applicable JOYSOUND models installed and apply, 10 people will be selected by lottery to receive an “RIIZE x JOYSOUND original tambourine.” Furthermore, if you sing “Sunburst” on the applicable models, you can also enjoy a special newly filmed comment video from RIIZE. Also today, a release commemorative showcase for the Japanese 3rd single “Sunburst” will be held. That event will be live-streamed on YouTube from 4:30 p.m. This showcase will consist of a mini live and talk, and is planned to include plenty of content such as the performance of “Sunburst” and talk that is unique to this day. In addition, a social media posting campaign commemorating the holding of the showcase will also be carried out. If you photograph your favorite scene from the showcase and apply by posting it on X, TikTok, or Instagram with the hashtag “#Sunburst_memoriize,” all participants will receive a “limited digital image.” ■Release information RIIZE The 3rd Japan Single “Sunburst” On sale Wednesday, August 26, 2026 Reservation/purchase here Details here ■Showcase streaming overview The 3rd Japan Single “Sunburst” release commemorative showcase streaming overview Streaming date and time: Wednesday, August 26, 2026, from 4:30 p.m. Streaming URL *There will be no archive release of this stream.
