 Sano returned to Japan and created Japan's own training course at Lake Yamanaka, near the base of Mount Fuji, called "Jisshu-sho", for both Cub and Scout leaders.The course is still used to this day, after completion of two preliminary courses, "Koshu-kai" and "Kenshu-kai".Sano then attended the 3rd World Scout Jamboree in the United Kingdom, and received the Silver Wolf award from Baden-Powell in 1931.
