History:

Asahi Sanbōdai is a complex of two year-round ski jumping hills located in the Asahi district of the city of Shibetsu on Hokkaido. For nearly four decades it has played an important role in Japan’s ski-jumping training system. The facility was built in 1988, before the administrative merger of Asahi with Shibetsu, and from the very beginning it was equipped with plastic matting, which made intensive summer use possible. Today the hills are owned by the city of Shibetsu, and their administration is handled by its education department responsible for sports development. The local community promotes this part of the city as a “training camp town,” where athletes of many disciplines practice throughout the year, with the ski jump being one of the key elements of the sporting infrastructure.
The complex includes two hills: HS 68 / K60 and HS 45 / K40. The larger hill is equipped with floodlights allowing evening training sessions and competitions. Alongside the smaller hill runs the characteristic “slope car,” a small incline railway that transports athletes to the top of the jump. The HS 68 profile features, among other elements, a 56-metre inrun, an inrun speed reaching about 70 km/h, and a landing slope with a gradient exceeding 30 degrees. The hills operate for most of the year—during summer from May to October, and in winter usually from December to February.
Since its construction, the complex has become one of the major training venues for the Yukijirushi Megmilk (Snow Brand) team, one of the most distinguished teams in the history of Japanese ski jumping. Among the athletes associated with this training base were Masahiko Harada, Takanobu Okabe, and Yūta Watase, long-time members of the Japanese national team. Due to the intensive use of the facility by Megmilk Snow Brand jumpers, Asahi Sanbōdai gained significance as a nationwide training centre. Symbolic ties to the hill were also highlighted by visits from Japanese female jumpers such as Sara Takanashi, Yuki Itō, and Kaori Iwabuchi, who appeared in Asahi during meetings with residents and local events.
Over the years, the hill has also developed as a competition venue. For decades it has hosted the All Japan Summer Jump Asahi Tournament, one of the oldest and most important summer competitions in Japan, often opening the national summer season. The HS 68 hill is also the site of nationwide junior and women’s championships, in which Sara Takanashi has frequently competed and taken victory. In recent years the facility has also hosted the junior Kuraray Sara Takanashi Cup, which attracts young athletes from all over the country. The calendar is complemented by local competitions, school tournaments, and Nordic combined events, with the ski jumping part held on the hill and the cross-country segment on the nearby Asahi Roller Ski Course.
The official records of the HS 68 hill are: 65.0 m by Ryota Yamamoto (set in the summer of 2011) and 67.0 m by Sara Takanashi (from 2012), which remains one of the longest confirmed jumps on this facility. The ski jump has undergone several modernisations, the most recent of which—carried out in 2024—was co-funded by the national sports lottery, confirming its continued importance within the sporting infrastructure of the region and the entire country.
