Japan Public Holidays
Japan's public holidays are set by the Act on National Holidays of 1948, which has since been amended many times. Several are tied to the seasons or the imperial family, and the equinox holidays shift by a day according to the astronomical calendar.

How public holidays work in Japan
When a national holiday falls on a Sunday, the following weekday becomes a substitute holiday, and a day sitting between two holidays is also treated as a holiday. Public holidays are the days most workplaces and schools in Japan treat as days off, so they shape when people travel, book time away and plan around childcare. Religious holidays and wider observances sit alongside them. They are not always days off, but they are dates many households still mark. Each year page lists the public and religious holidays in full, and OneHaus keeps the complete set current in your shared home calendar.
