The glamping facility 'Mieux Forest' in Uenohara City, Yamanashi Prefecture, operated by Aeon Fantasy Co., Ltd. (Headquarters: Chiba City, Chiba Prefecture; President and Representative Director: Tokuya Fujiwara; hereinafter 'our company') as a designated administrator, will celebrate its 3rd anniversary on Tuesday, July 21, 2026.
Taking the 3rd anniversary as an opportunity, the concept will be completely renewed to 'More Fun! More Casual!', transforming from the traditional style of 'enjoying provided services' into a 'co-creative glamping' experience where the guests themselves create their stay as the protagonists of a story.

■ Background: To increase children's 'I did it!' and 'fascination.' Experiential content doubled from last year.
We have given shape to the voices of parents, gathered from previous guests, such as 'I was moved to see my child act on their own' and 'Experiences that can only be had at Mieux Forest.' Every scene during the stay, such as meal preparation and cleanup, is converted into an 'Adventure (Activity)' that fosters children's autonomy and cooperativeness. By proposing the joy of families working together to clear missions as a new experiential value unique to Mieux Forest, our experiential content has doubled compared to last year! The number of experiences during the stay will be significantly expanded, broadening the 'I did it!' moments for children.
■ Evolution to 'More Fun' ①: [Experience UP] The entire stay is an adventure! 'Whole Stay Activities' starts 6/1~
Every scene during your stay will be transformed into an adventure, renewed as 'Quests' to clear in cooperation with family and friends.
・Mieux Forest Sleepover Quest Mission Card: The card handed out at check-in lists missions such as getting amenities and cleaning up after meals.
・Rewards for completing quests: Complete all missions to receive a special coin. You can use it in a capsule machine to get 'experiential novelties' (such as fish food or craft materials) that lead to the next experience.
■ Evolution to 'More Fun' ②: Fascinated even on rainy days. The 'Rainbow Atelier' for enjoying indoor workshops makes its debut! Starts 6/1~
