Since visiting Calgary Olympic Park and seeing their exhibit on ski jumping within the ski jumping tower, I've wanted to have a go at the sport, and Japan is the closest country to me (along with South Korea) that's into the sport.
Currently I know that lots of Japanese schoolkids learn ski jumping, and that English-language tourism sites mention ski jumping hills as sightseeing attractions (eg Okurayama in Sapporo and Hakuba).
What I don't know is whether it's possible to book ski jumping lessons (as in take lessons in the middle of the season for a week or so as part of a trip to Japan), or whether you'd have to be part of a sports club that operates for a whole season.
There doesn't seem to be any information in English about learning ski jumping in Japan, but maybe that's because people assume foreigners aren't interested in it.
Answers describing specific locations outside of Japan where it's possible to learn ski jumping are also welcome.
