I've seen a kangaroo jump. I've seen a video jump. I've even seen a record jump.
But until this September, I had never seen a ski jump.
A little ways from downtown Sapporo, on Okurayama, the Winter Sports Museum has artifacts and interactive stations about the games held in the cold part of year. The best part of the museum for me, though, turned out to be seeing this:
While I have some criticisms of the museum, that's because it's so good and so close to being great. If you find yourself in Sapporo, and are a fan of Olympic games or the sports you can find in them, it's worth a visit. But it takes about 20 minutes to get to Okurayama, where the museum and jump is located; buses to/from Sapporo Station run every 30 minutes or so, and also go by the zoo. Just ask where to get the bus toward 大倉山 (Okurayama). Admission is 600 yen, and the museum is open from 9:30 AM until 5:30 PM (6:00 PM May through October; Fridays and Saturdays until 9:00 PM June through September).
You can also take the ski lift to the top, which gives a better view of the launch area and (on clear days) the ability to see Sapporo and its surrounding countryside. I didn't use the ski lift, because a typhoon was moving in so it was rainy all day and the view was nonexistent. The fee is 500 yen round trip, or 250 yen one way. I guess you can walk back down, because I'm not taking the ski jump.
There's a Mongolian barbecue restaurant at the stadium, open for lunch 11:30-2:30 and dinner 5:30-9:30. The lunch menu is much cheaper, although you get a smaller portion. A building near the museum building, called the Crystal House, sells lots of souvenirs including Okurayama "exclusives" and several Hokkaido gifts. The Mongolian restaurant is located on the second floor of this building. Also, there is a cafe in the museum building.
If I can return to Sapporo, I will probably go back to the museum, if just to go to the top of the jump. Of course, timing the trip so that I can have lunch will be a priority.
