Tennin (天人), which may include tenshi (天使), ten no tsukai (天の使い, lit. heavenly messenger) and the specifically female tennyo (天女) are spiritual beings found in Japanese Buddhism that are similar to western angels, nymphs or fairies. They were imported from Chinese Buddhism, which was influenced itself by the concepts of heavenly beings found in Indian Buddhism and Chinese Taoism.
Tennin are mentioned in Buddhist sutras, and these descriptions form the basis for depictions of the beings in Japanese art, sculpture, and theater. They are usually pictured as unnaturally beautiful women dressed in ornate, colorful kimonos (traditionally in five colors), exquisite jewelry, and flowing scarves that wrap loosely around their bodies. They usually carry lotus blossoms as a symbol of enlightenment or play musical instruments such as the biwa, or flute.
Tennin are believed to live in the Buddhist heaven as the companions to the Buddhas and Bodhisattvas. Some legends also make certain tennin solitary creatures living on mountain peaks. Pilgrims sometimes climb these mountains in order to meet the holy spirits.
Tennin (天仁) was a Japanese era name (年号,, nengō,, lit. "year name") after Kajō and before Ten'ei. This period spanned the years from August 1108 through July 1110. The reigning emperor was Toba-tennō (鳥羽天皇).
