Nuru (Japanese: ぬる, lit. ‘slippery’) is Japanese erotic massage technique from Kawasaki, Japan. The technique requires one or more nuru masseuses to rub their body against the client’s body when both parties are nude and covered with an odorless and colorless massage lotion. The used gel is slippery, organic, made from nori seaweed.
During the massage, participants will try to get the widest possible physical contact, triggering strong tactile sensations designed to relieve stress. The main component of the gel used in nuru massages is the sulfated polysaccharide fucoidan, which is obtained from the leaves of the brown seaweed plant Sphaerotrichia divaricata. Chamomile, azulene and other minerals are often added. There are pre-made versions of nuru gel available as well as powdered versions.
Often, a nuru massage finishes with a sexual act. Along with other forms of sex work, nuru massages are legal in rural areas in Nevada, U.S., the Netherlands, Austria and some other countries.
