This book is the first by Noruhiro Takenouchi, who founded "Rirakuru," a relaxation shop seen on street corners all over Japan, and achieved great success, growing to over 600 directly managed stores in just seven years. It thoroughly details not only the behind-the-scenes of "Rirakuru"'s success but also the "business mindset" that allows him to successfully launch various businesses, which he continues to do. From his 20s as an active hairdresser, his 30s when he made "Rirakuru" a success, to his 40s as a business producer successfully running over 10 businesses in parallel, he shares his success know-how gained in each era. He introduces it with easy-to-understand examples, aimed at young people who want to start a business and business people who want to grow within an organization. His official YouTube channel, "President Takenouchi's Unconventional Success Laws," is a popular channel with 180,000 subscribers. He is also a regular on the popular YouTube channel "Reiwa no Tora CHANNEL." He is a notable business owner who receives constant requests for seminars and lectures.
