"Xiu Huo" Geeks Perfect Transformation into "Popularity King" + "Life Expert"

The author, Masafumi Ota, is an ordinary Japanese office worker and the founder and advocate of the "Kyūkats" (休活) lifestyle. In this book, he first introduces the concept of "Kyūkats." Kyūkats refers to a new way of life where ordinary people can use their free time on weekends to build networks and strengthen interpersonal relationships, gain experience and knowledge through days off, and promote health and deepen friendships by making the most of their leisure time.

Masafumi Ota is also a practitioner and advocate of the "Kyūkats" lifestyle. He transformed from being a homebody with "no friends, just moving between work and family" into a "popular person" who has built a network of over 1,000 people and hosts five study exchange meetings. It was this new "Kyūkats" lifestyle that brought about his astonishing transformation.

The book *Kyūkats* sold 180,000 copies in Japan within just one month of its publication, causing significant social impact and becoming a unique and popular self-help book. The "Kyūkats" concept presented in the book shares with readers how to fully utilize their leisure time to cultivate interests and contribute more help and value to society and others.
