Soine-ya is just sleeping with women, not sleeping with women. But for a price, you can rest your head on some woman's tush. A very steep price. There's a new service being offered called "Butt Pillow". The rate is ¥1,000 (US$11) per minute.
Recently, Japanese late night variety program News Flash! B-Grade News Show introduced the service. This reaction sums up the butt pillow pretty well.
