Sakurazawa Kei, a participant in the 0th term of the practical incubation studio "Musashino Valley Incubation Studio" (hereinafter referred to as MVIS) conducted by Musashino Valley Inc., has realized the Shibuya expansion of "Playground+", a place-making project conceived and practiced by urban architect Ken Shigematsu and others, which was provided in the program. Specifically, the limited-time event "Playground+ in Shibuya Sakura Stage", where adults and children can play healthily, will be held from July 10, 2026 (Fri) to July 16, 2026 (Thu) on the "Nigiwai STAGE" on the 3rd floor of Shibuya Sakura Stage, adjacent to Shibuya Station. MVIS is a practical startup studio that connects "high-quality ideas" with "challengers who want to create businesses", and provides comprehensive support for commercialization by top-tier instructors and mentors. The "Playground+" this time is the first business to be commercialized, based on an idea from Mr. Shigematsu by Mr. Sakurazawa, who proposed a business plan in the "0th term", the prototype of MVIS conducted from September to December 2025, and has undergone repeated verification and preparation. ■ What is "Playground+"? "Playground+" is an "adult playground" where people can enjoy drinks and food, play sports and games, and connect with others through natural conversations. It is a place-making project that has been repeatedly conceived and practiced by Ken Shigematsu and Zenta Mochizuki, President and CEO of Green Display Inc., which handles landscape and space production. It is also permanently deployed at "Mitz Kanazawa", which opened in May 2026 in collaboration with JR West Group and others. It aims to be a place where people of all ages, occupations, and nationalities can meet on an equal footing, combining the elements of "playing", "drinking", "eating", and "talking". The venue will feature areas where you can experience "Mölkky", a sport originating in Finland, and "Cornhole", a sport originating in the United St
