For many international visitors—especially travelers from the United States—the Emperor’s Birthday often raises practical questions: When is it held? What actually happens? And will it affect travel plans in Japan?
This guide answers those questions clearly and in one place. You’ll learn what the Emperor’s Birthday represents, why it is a national holiday, and why its date changes. We’ll also walk through what to expect on February 23, 2026, including Imperial Palace greetings, crowds, etiquette, and what’s open or closed—so you can plan your trip with confidence and cultural awareness.
What Is the Emperor’s Birthday in Japan?
The Emperor’s Birthday—called Tennō Tanjōbi (天皇誕生日) in Japanese—is a national public holiday that celebrates the birth of the reigning emperor of Japan. It is observed nationwide and recognized by law, meaning schools, government offices, and many institutions close or operate on a holiday schedule.
In modern Japan, the emperor is defined by the Constitution as “the symbol of the State and of the unity of the people.” The holiday is therefore not political in nature; instead, it emphasizes continuity, tradition, and shared national identity. For many Japanese people, it is a quiet holiday, while for visitors it is notable because of the rare opportunity to enter parts of the Imperial Palace grounds.
The holiday is unique in that its date changes when a new emperor ascends the throne. Unlike fixed holidays such as New Year’s Day, the Emperor’s Birthday always reflects the personal birthday of the current emperor.
When Did the Emperor’s Birthday Become a National Holiday?
The Emperor’s Birthday was officially established as a national holiday in 1948, following the enactment of Japan’s Public Holiday Law after World War II. This marked a clear shift toward Japan’s postwar constitutional framework, redefining the emperor’s role and how national celebrations are observed.
Before 1948, the emperor’s birthday was celebrated under the name Tenchōsetsu, particularly during the prewar period. While the celebration existed historically, its meaning and legal basis were different from today’s holiday.
The modern Emperor’s Birthday reflects postwar Japan’s emphasis on peace, symbolism, and constitutional order. It is now one of the country’s officially designated public holidays, alongside events such as Culture Day and Constitution Memorial Day.

When Is the Emperor’s Birthday? (2026 Date)
The Emperor’s Birthday is celebrated on February 23, and in 2026 it will also fall on February 23. The date is fixed as long as the current emperor remains on the throne.
This system explains why the holiday date can feel confusing to visitors. When a new emperor ascends, the holiday moves to match the new emperor’s birthday, and the previous date either disappears from the calendar or is reassigned to a different holiday.

How Japan Celebrates: Imperial Palace Greetings (Ippan-sanga)
One of the most distinctive features of the Emperor’s Birthday is Ippan-sanga, the public greeting event held at the Tokyo Imperial Palace. This is one of the very few days each year when members of the general public are allowed inside the inner palace grounds.
During Ippan-sanga, Emperor Naruhito and members of the imperial family appear on a balcony to offer short greetings to the crowd below. The atmosphere is calm, respectful, and celebratory rather than festive in a loud sense.
Visitors may also be invited to sign a greeting book, where attendees write their name, country, and a brief congratulatory message. For many travelers, this is a once-in-a-lifetime cultural experience that provides a rare glimpse into Japan’s living traditions.
