It's worse than that. Those Japanese businessmen are probably on corporate memberships, which entail a 1 million yen non-refundable initial fee, a 2.5 million yen deposit which is refundable only under certain conditions, and a 20,000 yen monthly fee. Oh, on top of that, they must pay 1,000 yen for every day they use the facilities. If you calculate it that way, $35 every time sounds like a bargain. You can see info here.
