Otaru K90

The Tenguyama ski jump in Otaru on Hokkaido was built in December 1926. The first professional competition was the Student Championships in 1928. The games were held in 1958, 1969, and 1970. The National Winter Sports Festival was held in 1952, 1962, and 1980. In 1967, another ski jump was built, and two hills, a K60 and a K90, were opened at that time. Both hills were demolished in 1999.
