Housed in the ski-jump stadium built for the Sapporo Olympics west of the central city, this highly amusing museum includes a computerised ski-jump simulator that allows you to try your skills without breaking every bone in your body. And if you do land a few virtual jumps, a chairlift ride to the launch point of the actual ski jump used in the 1972 games should serve as a quick reality check.
To reach the museum, take the Tōzai subway line to Maruyama Kōen (円山公園), and then take exit 2 for the Maruyama bus terminal. Next, take bus 14 to Ōkurayama-kyōgijō-iriguchi (大倉山競技場入り口; ¥200, 15 minutes); from here, it's a 10-minute walk uphill to the stadium.
