, or sōpu, is a Japanglish word constructed from the two English words " soap" and "land" and is part of Japan's nighttime entertainment industry, also known as Mizu shōbai.
Since sexual intercourse for money is officially prohibited in Japan, many different types of brothels in Japan have been developed. Although the main clientele for soaplands are males, there are also a few soaplands specifically for female clients.
There are various kinds of soaplands, and they are usually located in complexes with varying numbers of soaplands. Well-known complexes are located in Susukino in Sapporo, Yoshiwara and Kabukicho in Tokyo, Kawasaki, Kanazuen in Gifu, Ogoto in Shiga, and Fukuhara in Kobe, Sagaminumata in Odawara, and Nakasu in Fukuoka, but there are many other areas, especially in onsen ("hot springs") towns. Prices for a session at a soapland vary depending on location, time of day, and length of the session.
