“Ikoyo Festa 2026 in National Museum of Nature and Science” to Be Held on August 29–30, 2026!

ActInD Co., Ltd. (Shinagawa-ku, Tokyo; CEO: Norimichi Shimo moto), operator of the children and family outing information site “Ikoyo” (https://iko-yo.net/), will host the experiential event “Ikoyo Festa 2026 in National Museum of Nature and Science” free of charge on August 29 (Sat) and 30 (Sun), 2026, at the National Museum of Nature and Science in Chiyoda-ku, Tokyo. This event will be held concurrently with the “Ikoyo Science Private School Fair 2026.”

Ikoyo Festa 2026 is an experiential event where children can discover their personal interests. Developers and researchers from various companies will directly share their passion for products, technologies, and services with children through workshops and stage performances. These passionate adults are called “Sukisharists.” Together with children, they will conduct experiments, create objects, and explore mysteries—making it a special two-day event where both children and adults rediscover their passions.

This marks the third edition of Ikoyo Festa. The inaugural event at IMAGINUS in September 2025 attracted approximately 3,200 visitors over three days, while the March 2026 event at Tama Plaza Terrace drew over 2,100 visitors in a single day, both receiving high satisfaction ratings. Building on the connections and insights gained from these two events, Ikoyo Festa is expanding its stage to the National Museum of Nature and Science to bring smiles to even more families.
