Unagi Nobori is a rather strange drink made from eels. It has been launched in Japan with the translation of the name meaning "surging eel". The drink is a yellow liquid which contains eel extract and vitamins that are found in the fish. It has been launched to coincide with the start of Japan's annual eel eating season which starts on the 5th of August. Its main ingredients include extracts from the head and bones of eels, and five vitamins – A, B1, B2, D and E. Apparently it tastes similar to broiled eels, an acquired taste perhaps?
