Tenshindon

Tenshindon, also known as tenshinhan, is a Japanese [Chinese cuisine|Japanese Chinese] specialty, consisting of a crab meat omelette on rice, named after Tianjin in northern China.
Tenshindon is not known to be related to any dish in Tianjin cuisine, and both the origin of the dish and the reason it's named after Tianjin are contested. Records from the Taisho era mention a crab omelette dish called fuyō kani, where fuyō is the Japanese reading of egg [foo young|foo young], but not the name tenshindon. The earliest attested uses of the name date to after World [War 2], when the dish is said to have been invented by restaurateurs in either Tokyo or Osaka, possibly in reference to or inspired by soldiers returning from China.
