Every year on 11th February, Japan observes National Foundation Day, known in Japanese as Kenkoku Kinen no Hi (建国記念の日). This national holiday commemorates the legendary founding of Japan and the accession of its first emperor, Emperor Jimmu, to the throne in 660 BC. While historians regard this date as mythical rather than historical, the holiday serves as an important occasion for Japanese citizens to reflect on their nation’s heritage, cultural identity, and the remarkable continuity of the imperial line that has shaped their country for millennia.
The Legend of Emperor Jimmu
At the heart of National Foundation Day lies an ancient legend recorded in the Nihon Shoki (Chronicles of Japan), one of Japan’s oldest historical texts compiled in 720 AD. According to this chronicle, Emperor Jimmu was a descendant of the sun goddess Amaterasu, the most important deity in the Shinto religion. Born in Miyazaki Prefecture on the island of Kyushu, Jimmu embarked on an ambitious military campaign to unify the various tribes and clans scattered across the Japanese archipelago.
The legend portrays Jimmu as a courageous warrior who fought numerous battles against rival clans, ultimately achieving victory and establishing his rule. His eastern campaign, which led him from Kyushu to the Yamato region (present-day Nara Prefecture), is filled with mythological elements, including encounters with supernatural beings and divine guidance. A famous episode recounts how Jimmu saw a sacred golden bird, interpreted as a divine sign leading him to victory.
On the first day of the new year, according to the ancient lunisolar calendar, Jimmu ascended to the throne at Kashihara in what is now Nara Prefecture. This event, traditionally dated to 660 BC, marks what Japanese mythology considers the founding of the nation. While modern scholars view Emperor Jimmu as a legendary rather than historical figure, his symbolic importance in Japanese culture remains profound. He represents the divine origins of the imperial family and the unity of the Japanese nation under a single ruler.
From Empire Day to National Foundation Day
The story of how this ancient legend became a modern national holiday reflects Japan’s complex historical journey through modernisation, militarism, defeat, and reinvention.
The Meiji Era and Kigensetsu
During the Meiji Restoration (1868-1912), Japan underwent rapid modernisation and westernisation. The Meiji government sought to strengthen national unity and assert the emperor’s central role in Japanese identity. As part of this effort, they established Kigensetsu (紀元節), or Empire Day, as a national holiday in 1872.
The choice of date required some calculation. Since the original legend placed Jimmu’s accession on the first day of the lunar new year, Meiji-era historians had to convert this to the newly adopted Gregorian calendar. The date initially fell on 29th January 1873, but this proved problematic because many Japanese were still observing the traditional lunar calendar, causing confusion between Empire Day and Lunar New Year celebrations. To avoid this conflict, the government changed the date to 11th February 1873.
11th February held additional symbolic weight: on this same date in 1889, the Meiji Constitution (Constitution of the Empire of Japan) was promulgated, reinforcing the day’s association with national sovereignty and imperial authority. Empire Day became one of the most important occasions in the Japanese calendar, marked by grand celebrations, parades, and ceremonies emphasising loyalty to the emperor and national pride.
The holiday served a political purpose beyond mere celebration. The Meiji government promoted the concept of kokutai (national polity), an ideology emphasising the divine nature of the emperor and the unique character of the Japanese nation. Empire Day was designed to unite all Japanese people through their reverence for the god-emperor and foster a sense of shared national destiny.

Abolition After World War II
Following Japan’s defeat in World War II, the country underwent a fundamental political and social transformation under Allied occupation. The wartime government’s use of State Shinto and emperor worship to promote militarism and nationalism came under scrutiny. Empire Day, with its strong associations with the imperial cult and wartime ideology, was abolished in 1947 as Japan adopted its new pacifist constitution, which redefined the emperor’s role from divine sovereign to symbolic head of state.
For nearly two decades, Japan had no holiday specifically commemorating the nation’s founding. However, many conservative groups and citizens who valued traditional culture lobbied for the holiday’s reinstatement, arguing that the nation should have a day to reflect on its origins and cultivate patriotism, separate from the militaristic ideology of the wartime era.
Reinstatement in the 1960s
After years of debate, the government conducted a public opinion poll in 1966 to gauge support for reinstating the holiday. The survey of 8,700 respondents found that nearly half (47.4 per cent) favoured 11th February as the date for such a holiday, making it far more popular than alternative suggestions like 3rd May (Constitution Memorial Day) or 3rd April (anniversary of Prince Shotoku’s Seventeen-Article Constitution).
Based on this public support, the Diet (Japan’s parliament) revised the Public Holiday Law in 1966, officially establishing National Foundation Day. Importantly, the holiday was given a new name, Kenkoku Kinen no Hi rather than the old Kigensetsu, to distance it from its wartime associations. The law specified that the holiday’s purpose was to “cultivate a love for the country by commemorating the establishment of the country,” using language that emphasised patriotism while avoiding the imperial glorification of the earlier version.
National Foundation Day was first observed under its new name on 11th February 1967, marking the beginning of its modern incarnation as a more neutral celebration of Japanese national identity.
How National Foundation Day Is Celebrated Today
Compared to national days in many other countries, Japan’s National Foundation Day is a relatively understated affair. The celebrations reflect the holiday’s complex history and the diverse views Japanese citizens hold about nationalism and patriotism.
Official Observances
Since 2020, the “National Foundation Day Celebration Central Ceremony” has been held annually, organised by the “Japan’s National Foundation Day Celebration” organisation. This ceremony often includes attendance by ambassadors and dignitaries, though there is no official government-sponsored ceremony like those seen for some other national holidays.
One of the most visible official observances involves the Japan Maritime Self-Defence Force, which participates in a tradition known as “full dressing.” On National Foundation Day, self-defence ships moored at bases and ports around the country hoist the flag of the Maritime Self-Defence Force and colourful signal flags. After sunset, these vessels are illuminated, creating a spectacular display that honours the occasion.
The National Foundation Day Parade
The most prominent public celebration is the National Foundation Day Parade, held annually in Tokyo on 11th February. The parade typically begins at Meiji Park and proceeds along major streets including Gaien-Nishi Street, Aoyama Street, and Omote-Sando, before concluding at Meiji Shrine.
The parade features participants waving Japanese flags and carrying mikoshi (神輿), ornate portable shrines traditionally used in Shinto festivals. These shrines are continued the shoulders of groups of people, swaying rhythmically as they process through the streets. The parade represents a blend of patriotic expression and traditional religious practice, reflecting the holiday’s connection to both national identity and Japan’s indigenous Shinto faith.
Shinto Shrine Celebrations
Many Shinto shrines across Japan host special ceremonies called Kenkoku-sai (建国祭) or Kigensai (紀元祭) on National Foundation Day. These ceremonies typically involve ritual prayers, offerings to the kami (Shinto deities), and processions carrying portable shrines to and from the temple grounds.
The Kashihara Shrine in Nara Prefecture holds particular significance for this holiday. Built in 1889 at the site where Emperor Jimmu is said to have ascended to the throne, the shrine attracts many visitors on National Foundation Day who come to pay their respects and participate in special ceremonies. Reenactments of historical events, flag-raising ceremonies, and traditional performances often accompany the shrine festivities.
A Day of Rest
For most Japanese citizens, National Foundation Day functions primarily as a welcome day off from work and school. Many people spend the day quietly with family, taking advantage of the mid-week break to rest, enjoy leisure activities, or catch up on personal tasks. This low-key approach reflects a broader Japanese cultural tendency toward modest public displays of patriotism.
You will notice more Japanese flags flying from government buildings, some private homes, and businesses on this day, but the atmosphere is far more subdued than the fireworks and large-scale celebrations associated with national days in countries like the United States (Independence Day) or France (Bastille Day).
Political Dimensions
The holiday retains some political controversy. Due to its association with pre-war nationalism and State Shinto, some groups, particularly those on the political left, view National Foundation Day sceptically and may organise counter-demonstrations or educational events highlighting the dangers of nationalism. Occasionally, right-wing political groups use the day to promote their views, sometimes through sound trucks broadcasting nationalist messages through city streets.
Most Japanese, however, fall somewhere in the middle, viewing the holiday neither as an occasion for intense patriotic fervour nor as something to actively oppose. A 2015 survey revealed that only about 20 per cent of respondents knew that National Foundation Day was celebrated on 11th February, suggesting that for many, the historical and political significance of the date has faded into the background.
Practical Considerations for Visitors and Residents
For those living in or visiting Japan during early February, National Foundation Day has some practical implications:
Government Services and Banks: Government offices and most banks are closed on National Foundation Day, so any official business should be conducted before or after the holiday.
Transportation: Trains, subways, and buses operate on holiday schedules, which typically mean slightly reduced frequency during traditional rush hours, though service remains dependable and frequent enough for convenient travel.
Retail and Restaurants: Most shops, restaurants, and commercial establishments remain open, though some may have adjusted hours.
Tourist Attractions: Popular tourist destinations often experience higher visitor numbers on national holidays as Japanese families take advantage of the day off. Planning and arriving early at major attractions are advisable.
ATM Access: While most bank ATMs continue to function on holidays, they may charge small surcharges. It is wise to withdraw cash the day before if you anticipate needing it.
Cultural Etiquette: If you encounter parades, shrine festivals, or political demonstrations, observe respectfully and follow the guidance of local authorities or event staff.
The Symbolism and Meaning of National Foundation Day
National Foundation Day occupies a unique position in Japan’s calendar of public holidays. Unlike Constitution Memorial Day (3rd May), which celebrates Japan’s post war democratic constitution, or Culture Day (3rd November), which promotes arts and scholarship, National Foundation Day looks far back into legendary antiquity for its significance.
The holiday embodies a fundamental tension in modern Japanese identity: how to honour and preserve ancient traditions and cultural continuity while acknowledging the more problematic aspects of how those traditions were mobilised during the militaristic period. The transition from Empire Day to National Foundation Day represents an attempt to navigate this tension, keeping the core idea of commemorating national origins while removing the most overt connections to imperial ideology.
For Japan, a nation with one of the longest continuous cultural and political traditions in the world, National Foundation Day serves as a reminder of that extraordinary continuity. Whether or not Emperor Jimmu existed, and whether Japan was truly founded in 660 BC, the Japanese imperial line is demonstrably ancient. The current Emperor Naruhito represents the 126th generation of his family, a lineage that has been integral to Japanese identity for well over a thousand years.
At the same time, modern Japan is a constitutional democracy where the emperor serves a purely symbolic role. National Foundation Day asks Japanese citizens to reconcile these two aspects of their national identity, respect for ancient tradition and commitment to democratic values. For many, the holiday succeeds in this balancing act, providing a day to appreciate Japan’s unique history without glorifying the excesses of the past.
Comparing National Foundation Days Around the World
National Foundation Day invites interesting comparisons with similar holidays in other countries. Unlike Independence Day celebrations that commemorate liberation from colonial rule or revolutionary transformation, Japan’s National Foundation Day marks mythological rather than historical origins. In this respect, it resembles holidays like Australia Day or Canada Day, which commemorate specific but somewhat arbitrary dates in their nations’ development rather than dramatic founding moments.
The relatively modest nature of celebrations also sets Japan apart from many other nations. There are no large-scale fireworks displays, no extended festivities lasting days, and no intense public demonstrations of patriotism. This restrained approach reflects both the holiday’s contested history and broader cultural norms about appropriate expressions of national pride in post war Japan.
Looking Forward
As Japan continues to evolve in the 21st century, National Foundation Day’s meaning and significance will likely continue to shift. Younger generations, born decades after the war and far removed from the holiday’s original incarnation as Empire Day, may develop their own relationship with this day, potentially viewing it simply as an opportunity to appreciate Japanese culture and history without the weight of political controversy.
At the same time, ongoing debates about Japanese identity, the role of the emperor, and the country’s relationship with its past ensure that National Foundation Day will remain more than just another day off. It serves as an annual checkpoint for these larger conversations, a moment when Japan collectively considers questions about who they are as a nation and what values they wish to embody going forward.
Whether you encounter National Foundation Day as a Japanese citizen reflecting on your heritage, a long-term resident participating in local traditions, or a visitor observing the celebrations with curiosity, the holiday offers a window into Japan’s complex relationship with its past and its ongoing effort to honour tradition while embracing modernity. In that sense, National Foundation Day is not just about remembering a legendary emperor from antiquity; it is about understanding contemporary Japan’s place in the world and its vision for the future.
