A practice which began in the samurai period in Japan, Nyotaimori is the practice of serving sushi on the naked body. It can be done with a female model or a male model.

In traditional Nyotaimori, the model is generally expected to lie still at all times and usually not talk with guests until the event is concluded even after all food is removed.

The sushi is placed on sanitized leaves on the model's body to prevent skin-to-fish contact and on sufficiently flat areas of the body which the sushi will not roll off. In the Japanese style the geisha's body is fully naked except for traditional footwear and head dress. The Western style sometimes add covering such as a g-string. Nyotaimori is considered an art form
