"Hare Hare" (晴れ, lit. "clear weather") is TWICE's 10th Japanese single, digitally pre-released May 12, 2023 with the physical CD following May 31 via Warner Music Japan. The song was written specifically for TWICE's first stadium performances in Japan as part of the Ready to Be World Tour, giving it particular commemorative significance for collectors. The four-track release pairs the upbeat summer title track with B-side "Catch a Wave" and instrumentals of both. The single comes in twelve versions: Limited A (CD+DVD featuring jacket shoot making movie and member making video, 24-page lyric booklet, 1 of 10 trading cards, serial number), Limited B (CD, 4-page lyric booklet, group postcard + 3 of 9 member postcards, 1 of 10 trading cards, serial number), Regular (CD, 4-page lyric booklet, 1 of 10 trading cards on first press, serial number), and nine individual ONCE JAPAN fanclub member editions (one per member, each with 4-page lyric booklet, 3×3 fold poster, 2 selfie picture trading cards of 10 types, 2 serial numbers). The nine solo member fanclub editions make this one of the most version-heavy singles in the TWICE Japanese discography and a significant completionist challenge. The single debuted at #2 on the Oricon Singles Chart and #3 on the Billboard Japan Hot 100, sold over 135,000 physical copies in its first week, and received RIAJ Gold certifications for both physical shipments and streaming. It later appeared as the final track on the fifth Japanese studio album DIVE.
