Japan public holidays 2030

All 19 national holidays in 2030, and what each does to crowds at Japan's major sights. 10 land on a Monday, and 3 fall on a Saturday — which under Japanese law gets no substitute day.

The travel windows that actually matter

These aren't single holidays — they're multi-day periods when the whole country travels at once. They move crowds far more than an isolated public holiday does.

Golden Week — Mon 29 Apr 2030 to Mon 6 May 2030. The single worst week of the year to visit a major sight. Domestic travel peaks and prices follow.
Obon — Tue 13 Aug 2030 to Fri 16 Aug 2030. Family-travel season. Transport books out and cities empty while resorts and hometowns fill.

Common questions

How many public holidays does Japan have in 2030?

19, including substitute holidays. 10 fall on a Monday, creating three-day weekends, and 3 fall on a Saturday, which under Japanese law does not generate a substitute day off.

When is Golden Week 2030?

Mon 29 Apr 2030 to Mon 6 May 2030. It is the busiest domestic travel period of the year — expect major sights to be at their annual peak.

Do Japanese public holidays make tourist sights busier?

Substantially. A national holiday adds domestic visitors on top of the usual international ones, and a holiday adjacent to a weekend compounds it. KANAGI's forecasts fold every date on this page into the crowd score for all 70 landmarks it tracks.

A note on accuracy

Fixed-date and Happy-Monday holidays are exact — they follow statutory rules. The two equinox days are marked estimated: their dates are astronomically determined but only officially gazetted by the Cabinet Office about a year ahead, so anything beyond that is a computed projection rather than a confirmed date. Substitute holidays are derived from the rule that a Sunday holiday moves to the next day that isn't already one.
