Why do Japanese people display Samurai helmets on May 5th?

Hi, are you doing well ? It's already May!

So today let's talk about a Japanese traditional custom that's celebrated in May.

A long time ago, May 5th was a day in Japan when people would eat and decorate their homes with medicinal herbs. This is most likely in recognition and celebration of the changing of the seasons. During the 13th century, Samurai (Japanese warriors) held strong political powers, and so May 5th also became a day when people would celebrate samurai. Centuries later, may 5th finally became a day for celebrating boys, and to wish for their health and success.

And so, on May 5th, people have long been displaying Samurai helmets in their homes and hanging out flags in the shape of carps as a symbol of vivacity.

Nowadays, the 5th of May is called "Children's day" and is not only for boys.

But Japan has kept the tradition of celebrating this day in the following ways.

Hanging out Carp Flags "Koinobori"

People hang several carp flags outside their homes.

When the wind blows, these carps seem to be swimming in the sky!

Displaying Samurai Helmets

Samurai helmets are also displayed in homes. The prices of these helmets vary from thousands of yen, to as much as a million. (that's nearly 10,00 US dollars!)
