Seki Onsen is not as popular as it was in its hey day. Yet it has a certain appeal and was even featured recently on the Travel Channel's world ski series (Japan's only one). Although small, it's best not to ski off-piste here unless you are really sure what you're doing. For more information check out sekionsen.com (Japanese) or http://myoko-nojiri.com /ski.htm (English)
