When is Constitutional Memorial Day?

Also known as Constitution Day and 'Kenpo kinenbi' in Japan, this public holiday is part of Golden Week.

The Constitution of Japan came into force on May 3rd 1947.

To commemorate this event, the date is celebrated as a national holiday.

History of Constitutional Memorial Day

After Japan surrendered following the nuclear bombings of Hiroshima and Nagasaki, the country’s constitution was rewritten to emphasise peace and pacifism.

Unlike the Meiji Constitution that it replaced, the present Constitution declares that sovereignty lies with the people; the Emperor is "the symbol of the state and the unity of the people" who has no "powers related to government."

It asserts that people have fundamental human rights and renounce war. 

It is a very democratic document modeled on the American and British constitutions.
