BSJ N°6 – a ヘルス (“herusu”) is, for all intents and purposes, a brothel. It’s supposedly a health spa. I hear they deliver. The most Japanterous element to this is the name the Japanese used to use for it: a トルコ, or a "turoko", a Turkish bath. The reason for the name change? The Turkish ambassador complained. And the Japanese politely changed the word their brothel patrons use for brothels.
