Monaki, a Japanese J‑pop quartet formed in October 2023, originally assembled as a “second‑chance” project under producer Kazuki Sakai following a nationwide audition. The group-comprising Jin (born 1987‑02‑26), KenKen (born 1996‑07‑16), Sakai Jr. (born 1988‑12‑08), and Oyone (born 1997‑08‑15)-was formally introduced during a 2025‑11‑26 Junretsu concert and signed with G‑STAR.PRO. Monaki made its major debut on 2026‑04‑08 with the single "Honmayade ☆ Nandenande ☆ Shirankedo" and the EP Honmayade, Nandenande, Shirankedo /Konnamonjyanee, both released the same day. The debut track entered the Oricon weekly singles chart at number three with first‑week sales of 40,000 copies and topped the enka/song category. A social media campaign propelled the group to 282,000 followers and over 12.7 million likes, while the music video amassed 113.3 million views. Subsequent promotion included a Sunflower Fountain event in Tokyo, a 2026‑04‑29 solo show at Tsubo no Yō, and an announced Zepp tour in Osaka, Aichi, and Tokyo slated for August.
