In Japan, there is a culture to eat eels in “Doyou no ushi” day. “Doyou no ushi” day is a day defined in Japanese traditional calender. This year, July 19th is the day. In this day Japanese people rush to eel restaurant to have eels. Exciting, isn’t it?

This culture is made by Gennai Hiraga, a famous inventor in Edo period. People in Edo period did not eat eels in summer, and so the owner of eel restaurant asked Gennai how to sell eels in summer. Gennai’s idea was to make advertisement saying “Today is ‘Doyo no ushi’ day”. By this advertisement, people rushed to that eel restaurant believing that eating eels in “Doyo no ushi” day will help to gain power to overcome hot days in summer.

Today, it is proven that eating eels really help to gain power. Eels contain vitamin A and vitamin B a lot. So let’s eat eels and be healthy.
