RIIZE releases third Japanese single ‘Sunburst’

The boy group RIIZE has released their third Japanese single, ‘Sunburst’, on August 26. The title track is described as a house-based dance number with a refreshing summer mood, featuring rhythmic beats and synth sounds. The release marks their first new work in approximately six months since their second Japanese single, ‘All of You’.

The single also includes the track ‘Rise Over’, which serves as the official theme song for the SoftBank Winter Cup 2026 high school basketball championship, and ‘KILL SHOT’, which is the ending theme for the anime ‘Kill Ao’.

To celebrate the release, the karaoke service JOYSOUND is hosting a collaboration campaign. Customers who sing ‘Sunburst’ at participating locations can enter a drawing to win original RIIZE-themed tambourines and access special filmed comment videos from the group.
