KADOKAWA Corporation, headquartered in Chiyoda-ku, Tokyo and led by Director, Representative Executive Officer, President and CEO Takeshi Natsuno, released on Thursday, May 14, 2026 the first book by the day-service facility Rehashine Miyakonojo, which has more than 600,000 followers across social media: Idea Japan No. 1! Everyone’s Complete Recreation Book 100: Fun and Exciting Activities for Seniors! The book presents 100 recreation ideas that genuinely energized care-site participants, shared by Rehashine Miyakonojo, a facility that carries out more than 300 recreational activities each year and enjoys strong support on social media. It captures in one volume the facility’s challenge to transform care settings from Miyakonojo City in Miyazaki Prefecture. The book reached No. 1 on Amazon’s bestseller rankings in the Books categories of nursing care, care welfare studies, quizzes, puzzles, and games.

In a super-aged society, recreation at care facilities is essential for improving users’ quality of life. However, staff are busy with daily duties and have limited time to prepare activities. Users also voice concerns such as feeling as if they are being treated like children, or becoming bored when the content is the same every day. Rehashine Miyakonojo, a day-service facility in Miyakonojo City, Miyazaki Prefecture, practices more than 300 new recreation activities annually and shares successful examples on Instagram and other social media platforms. Its original ideas and scenes of users genuinely enjoying themselves have drawn comments and likes from around the world, and its Instagram account had more than 590,000 followers as of April 2026. Shuji Noda, managing director of Rehashine Miyakonojo Rehacare Wing and an occupational therapist, says the key to continuing is not overdoing preparation or ideation. The facility limits preparation to the 30 minutes immediately before the day’s activity begins, and avoids anything that takes longer. If preparation takes too much time, it burdens staff and creates pressure, which ultimately prevents them from truly enjoying the recreation. The tools and materials used are mostly familiar items such as facility benches and desks, bathroom baskets, and cardboard boxes from supplies used at the facility. When preorders opened and the book was introduced through Rehashine Miyakonojo’s social media channels, many people responded with comments such as “I want to use this as a reference,” “I want to buy a copy for our facility,” and “I’ve been waiting for this!” The book then reached No. 1 on Amazon’s bestseller rankings. The book also includes a message from facility director Koji Noda. Since opening in 2015, the facility has provided users with more than 300 types of recreation activities each year and began posting on Instagram in the hope of helping people struggling to come up with recreation ideas. By 2025, it had gained about 590,000 followers, and one of its recreation videos had been viewed more than 57 million times, a response comparable to the most-viewed Instagram video by HIKAKIN, one of Japan’s leading influencers. The book carefully selects the top 100 ideas that the facility has practiced on-site and that have been proven “fun” through the scrutiny of tens of thousands of social media viewers. The featured activities can be enjoyed regardless of age or gender, making them useful not only for care workers but also for playing with children at home, community events, nursery schools, kindergartens, and any setting where people gather and want to have fun together.
