A fizzy drink made from eels has been launched in Japan where it's said to be the best way to stay cool in hot weather.

Surging Eel is made by Japan Tobacco Inc and went on sale this month during the country's eel-eating season, reports Sky News.

"It's mainly for men who are exhausted by the summer's heat," said company spokesman Kazunori Hayashi.

The yellow-coloured fizzy drink contains extracts from the head and bones of eel plus five vitamins that are contained in the fish.

In Japan the demand for eel is so high that the country has been hit by a number of eel fraud cases.

Eel in Japan is often prepared in a style called 'kaba-yaki' in which it is broiled and covered in a sweet sauce.

The 65p drink costs about one-tenth as much as broiled eel but is said to have a similar flavour.
