Uniting Tradition and Modern Life in Japan
Japan is a country where tradition and modernity intertwine in everyday life. Among its many national holidays, one stands out not because of fireworks or parades, but for its deep historical roots and quiet cultural significance The Emperor’s Birthday. Known in Japanese as Tenno Tanjobi, the Emperor’s Birthday is not simply another public holiday. It is a day when the Japanese people reflect on national identity, express respect for their ceremonial leader, and gather as a nation to honor continuity and goodwill.
What Is the Emperor’s Birthday?
The Emperor’s Birthday is a national holiday in Japan celebrating the birth of the current Emperor of Japan. This holiday changes its date depending on the birthday of the reigning sovereign. Since Emperor Naruhito ascended the throne on May 1, 2019, the holiday has been observed on February 23, his birthday.
Although the Emperor no longer holds political power under Japan’s post-World War II constitution, the position remains a powerful symbol of the state and of the unity of the people. Celebrating his birthday has become a way for the nation to come together and appreciate the peaceful continuity of the Chrysanthemum Throne.
Traditionally, the Emperor’s Birthday was celebrated on different dates over Japan’s long history as emperors changed. For example, during the Shōwa era (Hirohito’s reign), it was observed on April 29, and during the Heisei era (Emperor Akihito), it was observed on December 23. When Emperor Naruhito became emperor, the holiday shifted to February 23.
How Is It Celebrated?
Celebrations for the Emperor’s Birthday combine public engagement, national pride, and ceremonial tradition.
One of the most significant customs takes place at the Tokyo Imperial Palace. On this day, the palace gates are opened to the general public a rare occurrence that normally happens only twice a year: on January 2 and on the Emperor’s Birthday. On the palace grounds, tens of thousands of visitors gather in the East Plaza (Tōtei) to see the Emperor, Empress and other members of the Imperial Family.
The highlight for many visitors is the public greeting from the palace balcony, where the Imperial Family appears several times during the morning to acknowledge well-wishers. Crowds wave small Japanese national flags, cheer, and sometimes shout “Banzai” a traditional exclamation wishing “long life”.
In the afternoon, visitors may also enter another section of the palace grounds to sign an official greeting book or leave messages of goodwill. The Imperial Household Agency arranges for thousands of visitors to participate, and the submitted messages are officially forwarded as expressions of respect and celebration.
