The 90 meter ski jump competitions of the Winter Olympics 1972 were held in the Okurayama Ski Jump Stadium (大倉山ジャンプ競技場, okurayama Janppu Kyogijo). Nowadays, when the stadium is not being used for world cup or other ski jump events, the Okurayama Observatory at the top of the hill can be accessed via a chair lift for spectacular views of Sapporo.
At the foot of the jump hill stands the Sapporo Winter Sports Museum with exhibits about the 1972 Sapporo Winter Olympics and winter sports in general, including ski jump, bobsled and biathlon. The museum has a variety of fun sport simulation games that cover events like ski jump, speed skating and hockey. The games can be played without any additional costs beyond the museum's entrance fee.
From late April to early November, the JR Burari Sapporo Kanko Bus runs about once per hour between JR Sapporo Station and the Okurayama Ski Jump Stadium (45 minutes, 200 yen). The bus can be used free of charge by Japan Rail Pass holders.
Around the year, it is possible to reach the ski jump from the Tozai Subway Line's Maruyama Koen Station (5 minutes, 200 yen, frequent departures from Odori Station) by bus. Take bus line 14 to Okurayama Kyogijo Iriguchi bus stop (10 minutes, 200 yen, 2 buses per hour), from where the ski jump is a ten minute walk uphill.
