From December to February: Why Did the Date of the Emperor’s Birthday Change?

A deep dive into Japan’s most significant imperial holiday, the historic 2019 abdication, and how travelers can experience this once-in-a-lifetime celebration

Introduction: Understanding Japan’s Changing National Holiday Calendar

Every nation has holidays that define its cultural identity, but few are as intimately connected to a living symbol of continuity as Japan’s Emperor’s Birthday (天皇誕生日, Tennō Tanjōbi). If you’ve been planning a trip to Japan or simply following Japanese culture, you may have noticed something peculiar: the date of this important national holiday recently shifted from December 23 to February 23.

This wasn’t a random bureaucratic decision. It represents one of the most significant events in modern Japanese history—the first imperial abdication in over 200 years. The transition from the Heisei era to the Reiwa era marked a turning point not just for the imperial family, but for the entire nation.

In this comprehensive guide, we’ll explore why the Emperor’s Birthday date changed, what it means for Japanese culture, and how you can experience this unique celebration firsthand. Whether you’re a history enthusiast, a Japan travel planner, or simply curious about one of the world’s oldest monarchies, this article will give you everything you need to know.

What is the Emperor’s Birthday in Japan and Why is it Celebrated?

The Emperor’s Birthday, known in Japanese as Tennō Tanjōbi, is one of 16 national holidays in Japan. It celebrates the birthday of the reigning monarch and is one of only two days per year when the general public can enter the inner grounds of the Tokyo Imperial Palace.

Historical Origins of the Imperial Birthday Celebration

The tradition of celebrating the emperor’s birthday dates back over 1,300 years. Historical records from Emperor Kōnin’s reign (775 CE) document early celebrations, though the custom likely stretches back even further. During the Heian period (794–1185), these celebrations were already an established part of court life.

Before World War II, the holiday was called Tenchōsetsu (天長節), a term derived from Chinese philosophy meaning “the longevity of heaven.” This name carried spiritual and divine connotations, reflecting the emperor’s status as a descendant of the sun goddess Amaterasu according to Shinto mythology.

After Japan’s defeat in World War II and the adoption of the 1946 Constitution, the emperor renounced his divine status. The holiday was officially designated as a national public holiday through the Holiday Act of 1948, transforming it from a religious observance into a secular celebration of Japan’s symbolic head of state.

The Three Emperor’s Birthdays: A Modern History of Changing Dates

Understanding why the Emperor’s Birthday moved from December to February requires understanding how the date is determined. Unlike many national holidays that are fixed to specific calendar dates, the Emperor’s Birthday always falls on the actual birthday of the reigning monarch.

This means the holiday changes whenever a new emperor ascends to the Chrysanthemum Throne—the poetic term for Japan’s imperial seat of power.

Emperor’s Birthday Dates Throughout Modern Japanese History

Key insight: When an emperor dies or abdicates, his birthday often remains a public holiday under a different name. This reflects Japan’s desire to preserve vacation days while honoring past monarchs.

Who is Emperor Akihito and Why Did He Abdicate the Throne?

Emperor Akihito (明仁), born December 23, 1933, reigned as the 125th Emperor of Japan from January 7, 1989, until his abdication on April 30, 2019. His 30-year reign, known as the Heisei era (meaning “achieving peace”), was marked by significant transformation both for Japan and for the imperial institution itself.

A Different Kind of Emperor: Akihito’s Revolutionary Approach

Unlike his father Emperor Hirohito, who was associated with Japan’s militaristic past, Akihito worked tirelessly to redefine the emperor’s role as a symbol of peace and reconciliation. He made unprecedented gestures toward former enemies and victims of Japanese aggression:

• Visited Saipan in 2005 to pay respects to both Japanese and American war dead
• Expressed “deep remorse” for Japan’s wartime actions during visits to China and Korea
• Personally comforted disaster victims after the 1995 Kobe earthquake and 2011 Tōhoku earthquake and tsunami

His compassionate approach earned him immense respect from the Japanese public. According to media surveys conducted before his abdication, public support for the imperial family reached 80%—the highest ever recorded.

The Historic Decision to Abdicate

On August 8, 2016, Emperor Akihito delivered a rare televised address to the nation. At 82 years old, he expressed concern that his advancing age and declining health would prevent him from fully carrying out his duties as emperor.

“I am concerned that it may become difficult for me to carry out my duties as the symbol of the State with my whole being, as I have done until now.” — Emperor Akihito, August 2016

This presented a significant challenge. Japanese law did not allow for imperial abdication. The last emperor to voluntarily step down was Emperor Kōkaku in 1817—over 200 years earlier.

After extensive deliberation, the Japanese Diet (parliament) passed the Emperor Abdication Law on June 8, 2017, creating a one-time exception to the Imperial Household Law. This historic legislation paved the way for the first voluntary imperial transition in modern Japanese history.

The 2019 Japanese Imperial Transition: From Heisei to Reiwa Era

The 2019 Japanese imperial transition was a carefully orchestrated series of ceremonies and rituals that captivated both Japan and the world. Unlike previous transitions, which occurred upon an emperor’s death and were associated with mourning, this was a celebration of continuity and renewal.

Timeline of the Historic Transition

The Japanese government declared a special 10-day Golden Week holiday from April 27 to May 6, 2019, allowing the nation to celebrate this historic moment.

What Does “Reiwa” Mean?

The era name Reiwa (令和) was announced on April 1, 2019. It combines two kanji characters:

• Rei (令): meaning “order,” “command,” or “auspicious”
• Wa (和): meaning “harmony” or “peace”

The official English translation provided by the Japanese government is “Beautiful Harmony.”

Notably, this was the first era name derived from Japanese classical literature rather than Chinese texts. The name comes from the Manyōshū, Japan’s oldest anthology of poetry compiled in the 8th century. This choice reflected a desire to emphasize Japan’s unique cultural heritage.

Who is Emperor Naruhito? Japan’s 126th Emperor Profile and Biography

Emperor Naruhito (徳仁) was born on February 23, 1960, in the Tokyo Imperial Palace. He became Japan’s 126th Emperor on May 1, 2019, at the age of 59.

Early Life and Education

Naruhito’s upbringing was notably different from previous generations of imperial children:

• First heir raised by his own parents — Breaking centuries of tradition, Crown Prince Akihito and Crown Princess Michiko chose to raise their children themselves rather than delegating to wet nurses and nannies
• Attended regular schools — Naruhito studied at Gakushūin schools in Tokyo, mixing with non-royal classmates
• First royal to study abroad — He spent two years at Merton College, Oxford University (1983–1985), researching the history of water transportation on the River Thames

His memoir about his Oxford experience, “The Thames and I: A Memoir of Two Years at Oxford,” reveals a humble, curious personality. In one memorable anecdote, he describes accidentally flooding a laundry room with soap bubbles during his first attempt at doing his own laundry.

A Passion for Water Conservation and Humanitarian Issues

Emperor Naruhito is recognized internationally for his expertise in water policy and conservation. This interest developed after a 1987 trip to Nepal, where he witnessed women and children struggling to collect water from a single tap.

His water-related activities include:

• Honorary president of the United Nations Secretary-General’s Advisory Board on Water and Sanitation (2007–2015)
• Keynote speaker at multiple World Water Forums
• Published academic research on historical water transportation systems
• Ongoing advocacy for addressing global water challenges

Beyond water issues, Naruhito has spoken on topics including climate change, disaster recovery, and cultural preservation. He and Empress Masako have worked to present a more accessible and relatable image of the imperial family.

Why is the Emperor’s Birthday Now February 23 Instead of December 23?

The shift from December 23 to February 23 was an automatic consequence of the imperial transition. Since the Emperor’s Birthday holiday celebrates the current reigning emperor’s actual birthday, the date changed when Naruhito succeeded his father.

The Year Without an Emperor’s Birthday: 2019

Here’s a fascinating quirk of the transition: 2019 was the first year since 1948 that Japan had no Emperor’s Birthday celebration.

Emperor Akihito abdicated on April 30, 2019—meaning his December 23 birthday occurred after he was no longer emperor. Emperor Naruhito’s February 23 birthday had already passed before his May 1 accession.

This created a unique gap in the holiday calendar that hadn’t occurred since the Holiday Act was introduced.

What Happened to December 23?

As of now, December 23 remains a regular working day in Japan. There has been discussion about whether it should become a new holiday (similar to how Emperor Hirohito’s birthday became Shōwa Day), but no decision has been made.

The Japanese government has been cautious about this decision because:

1. Emperor Akihito is still alive — Creating a holiday while the former emperor lives could be seen as treating him as deceased
2. Political considerations — Adding holidays has economic implications
3. Public sentiment — There’s debate about whether Japan needs more national holidays

How is the Emperor’s Birthday Celebrated in Japan Today?

The Emperor’s Birthday celebration combines ancient traditions with modern ceremonial practices. For the Japanese people, it’s both a day of national pride and a welcome day off work.

The Imperial Palace Public Greeting: Ippan Sanga

The highlight of the Emperor’s Birthday is Ippan Sanga (一般参賀), meaning “general public visit.” This is one of only two days per year (the other being January 2 for New Year’s greetings) when ordinary citizens can enter the inner grounds of the Tokyo Imperial Palace.

What happens during Ippan Sanga:

During each appearance, the Emperor—accompanied by Empress Masako and other imperial family members—steps onto a bulletproof glass-protected balcony to deliver a brief address thanking the gathered crowd.

The crowd responds by waving small Japanese flags (provided free at the gate) and shouting “Banzai!” (万歳), which literally means “ten thousand years” and expresses wishes for the emperor’s longevity.

COVID-19 Impact on Recent Celebrations

The public celebrations for Emperor Naruhito’s birthday were cancelled in 2020, 2021, and 2022 due to the COVID-19 pandemic. During these years, the Emperor addressed the nation through pre-recorded video messages and press conferences.

Full public celebrations resumed in 2023, marking the first Ippan Sanga for Emperor Naruhito’s birthday since becoming emperor.

The Cultural Significance of Former Emperor’s Birthdays Becoming New Holidays

One of the most fascinating aspects of Japan’s holiday system is how former emperor’s birthdays are preserved as national holidays under new names. This reflects the Japanese values of honoring ancestors while adapting to change.

April 29: From Emperor’s Birthday to Shōwa Day

Emperor Hirohito (posthumously Emperor Shōwa) was born on April 29, 1901. During his 63-year reign (1926–1989), this date was celebrated as the Emperor’s Birthday.

After his death in 1989, the date went through several transformations:

Today, Shōwa Day serves as the kickoff to Golden Week, Japan’s longest holiday period. It encourages citizens to reflect on the dramatic events of the Shōwa era—from World War II to Japan’s remarkable postwar recovery.

November 3: From Emperor’s Birthday to Culture Day

Emperor Meiji was born on November 3, 1852. His birthday was celebrated during his reign (1868–1912) and continued afterward.

After World War II, the holiday was renamed Culture Day (文化の日, Bunka no Hi) in 1948. Today it celebrates:

• Arts and academic achievement
• Freedom of thought and expression
• Japan’s cultural heritage

The government awards the Order of Culture to individuals who have made outstanding contributions to arts and sciences on this day.

The Japanese Imperial System: Understanding the World’s Oldest Monarchy

To fully appreciate the Emperor’s Birthday, it helps to understand Japan’s unique imperial system—the oldest continuous hereditary monarchy in the world.

A Timeline of Imperial History

The Emperor’s Role Today

Under the 1947 Constitution, the Emperor of Japan:

• Is the “symbol of the State and of the unity of the people“
• Has no political power
• Performs ceremonial duties (receiving ambassadors, opening Parliament, awarding honors)
• Serves as head of state for diplomatic purposes
• Cannot make political statements or express political opinions

The current imperial family includes:

• Emperor Naruhito (born 1960)
• Empress Masako (born 1963)
• Princess Aiko (born 2001, only child of the imperial couple)
• Crown Prince Akishino (Emperor’s younger brother, heir to the throne)
• Princess Kako (daughter of Crown Prince Akishino)

Note: Under current Japanese law, only males in the paternal line can inherit the throne. This has sparked ongoing debate about potential reforms to allow female succession.

How Does Japan’s Emperor’s Birthday Compare to Other Royal Birthday Celebrations?

Royal birthday celebrations exist in monarchies around the world, but Japan’s approach is uniquely tied to its cultural identity.

Comparison of Royal Birthday Holidays

Key difference: Unlike the UK, which sets the monarch’s “official birthday” on a convenient early summer date, Japan celebrates the actual birthday of its emperor—meaning the holiday date changes with each new reign.

Planning Your Japan Trip Around the Emperor’s Birthday: Travel Tips and Recommendations

Visiting Japan during the Emperor’s Birthday offers a unique window into Japanese culture that few tourists experience. Here’s how to make the most of it.

Best Areas to Stay in Tokyo for Emperor’s Birthday

What’s Open and Closed on Emperor’s Birthday

Closed:

• Government offices
• Banks (though ATMs at convenience stores operate normally)
• Post offices
• Some small family-run businesses

Open:

• Department stores
• Supermarkets
• Most restaurants
• Theme parks and tourist attractions
• Convenience stores (7-Eleven, Lawson, FamilyMart)

Transportation: Trains and subways run on a Sunday/holiday schedule, meaning slightly reduced frequency but full coverage throughout the day.

Combining Emperor’s Birthday with Other February Attractions

If you’re visiting Japan for the Emperor’s Birthday, consider extending your trip to experience:

• Plum blossom season (mid-February to early March) — Beautiful plum gardens at Kairakuen in Mito or Kitano Tenmangu in Kyoto
• Sapporo Snow Festival (early February) — Spectacular ice sculptures in Hokkaido
• Setsubun (February 3) — Temple ceremonies marking the transition from winter to spring
• Valentine’s Day (February 14) — In Japan, women give chocolate to men (men reciprocate on White Day, March 14)

The Future of Japan’s Imperial System and the Emperor’s Birthday

As Japan moves further into the Reiwa era, several questions remain about the future of the imperial institution and its associated holidays.

Succession Concerns and Potential Reforms

The current Imperial Household Law, enacted in 1947, restricts succession to males in the direct paternal line. This has created concern because:

• Emperor Naruhito has no sons — His only child is Princess Aiko
• Only one young male heir exists — Prince Hisahito (born 2006), son of Crown Prince Akishino
• The imperial family is shrinking — Female members lose their royal status upon marriage to commoners

Public opinion polls consistently show majority support for allowing female emperors, but the government has been cautious about constitutional changes.

Will December 23 Become a Holiday Again?

Discussions continue about whether to establish December 23 as a new national holiday. Possibilities include:

1. Creating “Heisei Day” — Similar to Shōwa Day, commemorating the Heisei era
2. Leaving it as a regular day — At least while Emperor Emeritus Akihito is still living
3. Designating it for a specific purpose — Such as a day for reflection on disaster preparedness (referencing the 2011 Tōhoku disasters that defined much of the Heisei era)

No timeline has been announced for any decision.

Experiencing Japan’s Living History: Why the Emperor’s Birthday Matters

The Emperor’s Birthday is more than just a day off work for the Japanese people. It represents:

• Continuity — The unbroken imperial line stretching back over 2,600 years (according to tradition) or at least 1,500 years (according to historical records)
• Unity — The emperor as a symbol binding together Japan’s 125 million people
• Tradition meeting modernity — Ancient Shinto rituals performed by a 21st-century family
• Accessibility — A rare opportunity to personally encounter Japan’s head of state

For international visitors, attending the Emperor’s Birthday celebrations offers an unparalleled glimpse into Japanese culture—the respectful silence of crowds, the precision of ceremonial procedures, the genuine emotion of citizens wishing their emperor well.

Conclusion: Understanding the Significance of Japan’s Shifting Imperial Calendar

The move of the Emperor’s Birthday from December 23 to February 23 wasn’t just a calendar change—it was a historic transition that happens only once or twice per century. The 2019 imperial transition marked:

• The first abdication in over 200 years
• The end of the 30-year Heisei era
• The beginning of the Reiwa era under Emperor Naruhito
• A peaceful, celebratory succession rather than a mourning period

Whether you’re planning to visit Japan during the Emperor’s Birthday, researching Japanese culture, or simply curious about one of the world’s most unique holiday traditions, understanding this change connects you to Japan’s living history.

Emperor Naruhito’s birthday—February 23—will remain Japan’s Emperor’s Birthday for as long as he reigns. When that changes again, it will mark another chapter in the world’s oldest continuous monarchy.

For now, every February 23, the Japanese people gather to wish their emperor “Banzai!”—ten thousand years of health and prosperity. And at the Tokyo Imperial Palace, the Chrysanthemum Throne’s ancient traditions continue into the modern age.

Frequently Asked Questions About Japan’s Emperor’s Birthday

Why did Japan’s Emperor’s Birthday change from December to February?

The Emperor’s Birthday in Japan is always celebrated on the actual birthday of the reigning monarch. When Emperor Akihito abdicated on April 30, 2019, and Emperor Naruhito ascended to the throne on May 1, 2019, the holiday automatically shifted from December 23 (Akihito’s birthday) to February 23 (Naruhito’s birthday).

Is December 23 still a holiday in Japan?

No, December 23 is currently a regular working day in Japan. There are discussions about whether to make it a new holiday (similar to how April 29 became Shōwa Day), but no decision has been made as of 2025.

Can foreigners attend the Emperor’s Birthday celebration at the Imperial Palace?

Yes! The Ippan Sanga (public greeting) is open to everyone—Japanese citizens and foreign visitors alike. There’s no admission fee, and you may sign the Greeting Book to offer congratulations to the Emperor.

How many people attend the Emperor’s Birthday at the Imperial Palace?

Typically, tens of thousands to over 100,000 people attend throughout the day. The event is extremely well-organized, with police managing crowd flow efficiently.

What is the difference between the Emperor’s Birthday and the New Year Greeting?

Both events feature the imperial family appearing on the palace balcony. The New Year Greeting (January 2) has five appearances and focuses on wishing for a prosperous year. The Emperor’s Birthday has three appearances and celebrates the monarch specifically. Both are the only days the inner palace grounds are open to the public.

When was the last time an emperor abdicated before 2019?

The last voluntary abdication was Emperor Kōkaku in 1817—over 200 years before Emperor Akihito’s abdication. The 2019 transition was truly historic.

The Economic Impact of the Emperor’s Birthday on Japanese Tourism

The Emperor’s Birthday doesn’t just hold cultural significance—it also has measurable economic effects on Japan’s tourism and retail sectors.

Tourism Boost in February

February has traditionally been a slower tourism month for Japan, falling between the popular New Year period and the cherry blossom season (late March–early April). The Emperor’s Birthday creates a natural focal point for winter visitors interested in cultural experiences.

Benefits for tourists visiting during this period:

Retail and Business Considerations

For businesses operating in Japan, the Emperor’s Birthday affects operations:

• Three-day weekend (when February 23 falls on a Friday or Monday) boosts domestic travel
• Department stores often run special sales and promotions
• Restaurants near the Imperial Palace experience significantly higher traffic
• Hotels in central Tokyo may charge premium rates around the holiday

The Role of the Imperial Family in Modern Japanese Society

Understanding the Emperor’s Birthday requires appreciating the unique position the imperial family holds in contemporary Japan—respected yet distant, ceremonial yet deeply meaningful.

Public Appearances and Accessibility

Unlike many European royals who maintain active social media presence and regular public visibility, the Japanese imperial family appears in carefully controlled, formal settings:

• National holidays (Emperor’s Birthday, New Year’s Greeting)
• State visits by foreign leaders
• Disasters and tragedies (offering condolences and visiting affected areas)
• Cultural events (concerts, exhibitions, academic ceremonies)
• International conferences (particularly on topics like water issues for Emperor Naruhito)

This limited visibility actually enhances the special nature of opportunities like the Emperor’s Birthday public greeting.

The Imperial Household Agency: Guardians of Tradition

The Imperial Household Agency (宮内庁, Kunaicho) manages all aspects of the imperial family’s public life. This government agency:

• Coordinates the Emperor’s schedule
• Manages Imperial Palace grounds and facilities
• Organizes public ceremonies
• Handles media relations
• Preserves imperial traditions and protocols

The agency is known for its conservative approach and has sometimes been criticized for isolating imperial family members from public life. However, Emperors Akihito and Naruhito have both worked to expand public engagement within these traditional constraints.

Empress Masako: A Modern Imperial Consort’s Journey

No discussion of Emperor Naruhito’s reign would be complete without acknowledging Empress Masako, whose personal story has captivated Japan and the world.

From Diplomat to Empress

Masako Owada was born on December 9, 1963, in Tokyo. Her background was remarkably different from typical imperial brides:

• Educated abroad — Attended schools in Moscow, New York, and Boston
• Harvard graduate — Earned a degree in economics
• Oxford scholar — Studied international relations at Balliol College
• Career diplomat — Worked at Japan’s Ministry of Foreign Affairs

Crown Prince Naruhito reportedly proposed multiple times before Masako finally accepted in 1992. She was initially reluctant to give up her diplomatic career and independence.

Struggles and Resilience

After their 1993 wedding, the pressure to produce a male heir—combined with intense media scrutiny and strict palace protocols—took a toll on Masako’s mental health. She was diagnosed with an adjustment disorder in 2004 and significantly reduced her public appearances.

Since becoming Empress in 2019, Masako has gradually increased her public visibility, appearing alongside Naruhito at state functions and international events. Her recovery has been celebrated by the Japanese public as a symbol of resilience and hope.

Regional Celebrations: How Different Parts of Japan Mark the Emperor’s Birthday

While the main celebration centers on Tokyo’s Imperial Palace, the Emperor’s Birthday is observed throughout Japan in various ways.

Local Government Observances

The Hinomaru: Japan’s National Flag

• Government buildings
• Schools
• Businesses
• Private homes (in more traditional neighborhoods)
• Public transportation vehicles

The flag represents the sun, connecting symbolically to the emperor’s traditional descent from the sun goddess Amaterasu.

International media, including outlets like NHK World, often provide English-language coverage for global audiences.

The Emperor’s Birthday in Japanese Popular Culture

The Emperor’s Birthday has appeared in various forms of Japanese media and popular culture, though often indirectly due to sensitivities around depicting the imperial family.

Literature and Film

Understanding Japanese Holiday Law and the Imperial Birthday System

For those interested in the legal framework behind Japan’s holidays, the Emperor’s Birthday operates within a specific legislative structure.

The Holiday Act of 1948

The National Holiday Law (国民の祝日に関する法律) established Japan’s post-war holiday calendar. Key provisions:

1. Holidays falling on Sunday are observed on the following Monday (“substitute holiday” system)
2. If a single day falls between two holidays, it becomes a holiday by default
3. The Emperor’s Birthday is explicitly designated based on the reigning monarch

How New Holidays Are Created

Creating or changing national holidays requires:

1. Proposal — Typically from the Cabinet or Diet members
2. Committee review — Diet committees examine economic and social impacts
3. Full Diet vote — Both houses must approve
4. Imperial approval — Formal promulgation by the Emperor (ceremonial only)

This explains why December 23’s status remains uncertain—changing the holiday calendar is a significant political and bureaucratic process.
