KEIJU - Oiwai

November 1st, 2026 | Tokyo, Japan | Team RJHH

KEIJU releases “Oiwai (お祝い / Celebration)” on November 4 via Cashcade Entertainment, his own label. One track, 2 min 35. The single is already placed on Apple Music’s Hip-Hop: Japan, New in J-Pop and The New Asia playlists.

“Oiwai” lands after twelve busy months. KEIJU released the album N.I.T.O. in May 2025, twelve tracks partly produced by Xansei, with 7 and Gottz, his former KANDYTOWN partners. The tour that followed ended on January 25, 2026, at Pia Arena MM in Yokohama, a 10,000-capacity venue. That night, OKAMOTO’S joined him on stage for “Seasons,” a joint track released on February 11, mixed by Illicit Tsuboi and mastered by Collin Leonard. Since then, KEIJU has kept up a run of features: “Friends, Family & God” with G-k.i.d, “Money Baby” with Awich, “Backseat” with Kvi Baba and tofubeats. “Oiwai” is his first track alone since that sequence.

Oiwai means a celebration in Japanese, or the gift you give to mark a happy event. A wedding, a birth, a promotion. Applied to a rapper who just filled an arena and closed an album cycle, the title reads on its own. I did not have access to the official lyrics, so I don’t go into the text.
