In 1924, Japan fielded a full contingent of 25 to the 2nd World Scout Jamboree in Denmark. Tsuneha Sano was a participant, during which time he attended a Wood Badge course at Gilwell Park, marking the watershed for the first period of Japanese Scouting. In 1925 Sano returned to Japan and created Japan's own training course at Lake Yamanaka, called Jisshu-sho, for both Cub and Scout leaders, which is still used to this day, after completion of two preliminary courses, Koshu-kai and Kenshu-kai. Count Sano discovered clean water there, opened a camp and a leaders training center, which after World War II became a national practical training center, with special training for Fuji Scouts, base camp for hiking Mount Fuji, and year-round camping for Scouts from across Japan and abroad.
