Risako (凛咲子), nicknamed Ri-chan, is a Fukuoka-born Japanese gravure idol, actress, and talent who moved to Tokyo in 2020 after vocational school and is managed by TRUXiA. She debuted in November 2021 with the DVD Ri-chan’s Summer, won the grand prix of the 3rd Sanspo GoGo Queen, and later released the 149-page First Gravure photobook PICTURA (Latin for “painting”) on January 10, 2026, a three-day shoot at Isone Coast, the forests of Ome, and quiet riverbanks in which she traded her usual “fresh” image for more elegant, mature looks; since May 2025 she has also been a K-1 GIRLS round girl, debuting at K-1 WORLD MAX 2025 in Yokohama. Off camera she watches and plays basketball, follows movies and anime, and posts in Hakata dialect on Instagram (@ri__mopi_7), TikTok (@risako_s2), and X (@ris2_channel)—together past half a million followers by late 2025—mixing daily clips, lives, pool photo events, and fan trips such as Traberry, with baking sweets on YouTube as her next stated challenge.
