Shibuya Taiiku Souko (渋谷体育倉庫)

Shibuya Taiiku Souko ("Shibuya gym storeroom") is a men-only cruising club (hattenba) in Maruyama-chō, a few minutes' walk uphill from Shibuya Station. Hatten.jp and Mr.Cruising both list it, and it shares a phone number with Shibuya Street, so it appears to be the same operator. Google places it at 2-9 Maruyama-chō. Listed hours are 13:00–23:00 Monday to Thursday, from 13:45 on Fridays and 12:30–22:00 at weekends. Google reviewers rate it 2.3 from about 28 reviews, mostly over entry rules. Like most Tokyo hattenba it may have age limits and can refuse foreigners, so check its site (taiikusouko.com) first.
