Japan has 16 public holidays a year, more than any other G7 country. They are set by the Act on National Holidays of 1948, which has been amended repeatedly to add new ones, and the calendar contains two mechanisms found almost nowhere else: a rule that moves several holidays to Mondays, and a rule that turns any ordinary weekday caught between two holidays into a holiday itself. Together they produce Golden Week, the busiest travel period in the country.

The Happy Monday System
Four of Japan's holidays float to a Monday rather than falling on a fixed date. Coming of Age Day is the second Monday in January, Marine Day the third Monday in July, Respect for the Aged Day the third Monday in September, and Sports Day the second Monday in October.
The arrangement was introduced in 2000 and extended in 2003, and it is officially called the Happy Monday System — that is the term used in Japanese legislation and press coverage, not a translation joke. The purpose was to create three-day weekends and encourage domestic tourism.
It was not universally welcomed. Coming of Age Day had been fixed to 15 January since 1948 and Sports Day to 10 October, the date of the 1964 Tokyo Olympics opening ceremony, and moving them was criticised for detaching the holidays from what they commemorate.
The Day That Becomes a Holiday by Accident
Article 3 of the holidays act contains a provision with no clear equivalent anywhere else: any day that falls between two public holidays becomes a public holiday itself. It is called kokumin no kyūjitsu, a citizens' holiday.
The classic case was 4 May, which sat between Constitution Memorial Day on 3 May and Children's Day on 5 May. It was a holiday for years without having a name of its own, before being formally designated Greenery Day in 2007.
The rule still operates. Silver Week, an occasional five-day break in September, happens when Respect for the Aged Day falls on the third Monday and the Autumnal Equinox lands on the Wednesday, making the Tuesday between them a holiday. The alignment occurred in 2009, 2015 and 2026 and will not recur for several years after.
Golden Week
Four holidays fall between 29 April and 5 May: Showa Day, Constitution Memorial Day, Greenery Day and Children's Day. With weekends and the citizens' holiday rule, the cluster produces a break of seven to ten days depending on the year.
It is the largest domestic travel period in Japan. Shinkansen services run at over 100% of seated capacity, flight and hotel prices multiply, and the expressways report traffic jams measured in tens of kilometres. Many companies close entirely.
The Japanese government has periodically discussed staggering Golden Week by region to spread the load, and the idea has never been adopted. The concentration is the point for most workers, because taking leave outside a company-wide shutdown remains socially difficult.
The Equinoxes Are Holidays
Japan is one of very few countries with public holidays determined by astronomy. Vernal Equinox Day in March and Autumnal Equinox Day in September fall on the actual equinox, which means the date is not known far in advance.
The National Astronomical Observatory of Japan calculates the equinox instants and the Cabinet publishes the following year's dates in the official gazette each February. Until that announcement, the following year's calendar is technically provisional.
Both days coincide with higan, the Buddhist observance in which families visit ancestral graves. They were called Shunki and Shūki kōreisai — imperial ancestor festivals — before 1948, and were renamed and secularised in the postwar reform.
Substitute Holidays
If a public holiday falls on a Sunday, the following Monday becomes a substitute holiday, a rule called furikae kyūjitsu introduced in 1973. Saturdays do not get a substitute, which is a common source of complaint since a Saturday holiday is simply lost.
The rule was strengthened in 2007 so that the substitute is the next non-holiday day rather than strictly the Monday, which matters when several holidays fall close together.
Combined with the Happy Monday System and the citizens' holiday rule, the Japanese calendar has more moving parts than almost any other. Japanese diaries and calendars mark holidays in red and are updated annually because the pattern genuinely changes.
Obon Is Not a Public Holiday
The most significant break in the Japanese year after New Year is Obon, the Buddhist festival honouring ancestors, observed in mid-August in most of the country. It is not a public holiday.
Businesses close anyway. Most companies shut for three days or more around 13 to 15 August, transport runs at Golden Week levels, and the return to the cities produces the second-largest traffic jams of the year. Mountain Day, established in 2016 and fixed to 11 August, was placed there partly to formalise the start of the Obon period.
The same applies to New Year. Only 1 January is a public holiday, but government offices close from 29 December to 3 January by separate regulation, and most private businesses follow.
The Holidays That Were Renamed
Several Japanese holidays are pre-war observances that were kept and rebranded after 1945. National Foundation Day on 11 February was Kigensetsu, marking the mythical accession of Emperor Jimmu in 660 BCE; it was abolished by the occupation authorities in 1948 and reinstated under a new name in 1966.
Culture Day on 3 November is the birthday of the Meiji Emperor and was called Meisetsu; it now marks the promulgation of the postwar constitution on that date in 1946. Labour Thanksgiving Day on 23 November was Niinamesai, the imperial harvest ritual, which the Emperor still performs.
Showa Day on 29 April is the birthday of Emperor Hirohito. It was Greenery Day between 1989 and 2006, and was renamed Showa Day in 2007 with Greenery Day moved to 4 May — a rearrangement that took nearly two decades of parliamentary argument.
The Emperor's Birthday Moves With the Emperor
The Emperor's Birthday is the one holiday whose date changes with the occupant of the throne. It was 29 April under Hirohito, 23 December under Akihito, and has been 23 February since Naruhito's accession in 2019.
2019 was consequently unusual: there was no Emperor's Birthday holiday at all, because Akihito abdicated on 30 April before his December birthday and Naruhito's February birthday had already passed. The accession itself produced a one-off ten-day Golden Week that year.
On the day, the Imperial Palace opens its inner grounds and the imperial family appears on a balcony behind glass to greet the public. The only other day this happens is 2 January.
How Much Time Off Japanese Workers Actually Get
Sixteen public holidays is generous, and it partly compensates for something else: Japan has one of the lowest rates of annual leave usage in the developed world. Government surveys have long found take-up of statutory paid leave running around 50 to 60%, though it has risen since a 2019 law obliged employers to ensure workers take at least five days.
Statutory paid annual leave starts at ten days after six months of employment and rises with service to a maximum of twenty. Public holidays are not legally required to be paid days off in the private sector, though in practice almost all employers treat them as such.
The result is a calendar in which time off is largely collective and scheduled rather than individually chosen. Golden Week and Obon exist as mass phenomena because everyone takes them at once.
Holidays That Were Added Recently
Japan's holiday count has grown steadily. Marine Day was added in 1996, Mountain Day in 2016, and Sports Day was renamed from Health and Sports Day in 2020.
Several were moved for the Tokyo Olympics. Marine Day, Mountain Day and Sports Day were all shifted in 2020 and again in 2021 to align with the opening and closing ceremonies, by special legislation passed for each year.
Mountain Day is the newest and had no historical basis at all — it was proposed by mountaineering associations and adopted because Japan had a Marine Day and no equivalent for its mountains, which cover around three-quarters of the country.
