Les Trois Graces Inc. announced that it will hold a public recording of Nippon Broadcasting System’s All Night Nippon GOLD during Sustainable Beauty Fes 2026, taking place on May 23 and 24, 2026, at Kawaguchiko Stellar Theater in Yamanashi Prefecture. Singer AI will appear as a guest, and highlights from the festival will air nationwide on May 29 at 10 p.m. The May 23 performance will feature a collaboration with All Night Nippon GOLD under the title Ko Shibasaki’s All Night Nippon GOLD: Sustaina Beauty RADIO supported by Asahi Gold. Ko Shibasaki will be joined by guest AI and partner Saki Yagi for a special talk session in the atmosphere of the festival. The broadcast will also include live audio from the event, artist talk sessions, and coverage of sustainability booths at the venue. The program is currently accepting listener messages on two themes: “I started because it was fun!” and “Something that made me feel positive.” Shibasaki commented that she had previously spoken on air about wanting to create something like a festival where everyone could gather, and she is delighted that it is now becoming reality. She hopes the broadcast will share the sights and feelings of the venue with both attendees and those unable to attend. Across both festival days, the finale will feature an audience participation event titled HAPPY GOLD HOUR ~KANPAI CORNER~. Created in collaboration with official sponsor Asahi Gold, the event invites Shibasaki and attendees to raise a drink together in the outdoor venue surrounded by Mount Fuji and Lake Kawaguchi, embodying the festival theme, “Let’s start because it’s fun.” Attendees are asked to prepare their own drinks in advance from the venue’s food and shop areas; drinks will not be distributed by the organizer. Visitors under 20 and those arriving by car must choose non-alcoholic drinks. Official merchandise will go on sale at the venue from 11 a.m. on both May 23 and 24. Six items will be available, including an Imabari scarf towe
