Greenery Day Description
Greenery Day (みどりの日, Midori no Hi) on May 4th celebrates nature and the environment, encouraging appreciation of the natural world. The holiday's history reflects Japan's evolving national calendar: originally, April 29th was celebrated as Greenery Day during the reign of Emperor Akihito (due to his passion for biology and nature), but was moved to May 4th in 2007 when April 29th was redesignated as Showa Day. The holiday falls within Golden Week, ensuring it is always part of the extended spring vacation period. National parks, botanical gardens, and urban green spaces are popular destinations, with many offering free admission. The Imperial Palace East Gardens and Shinjuku Gyoen National Garden in Tokyo are especially busy. Municipal tree-planting ceremonies and nature workshops are held in communities across Japan. Government offices and schools close. In 2026, since Constitution Memorial Day (May 3rd) falls on a Sunday, Greenery Day also functions as the substitute holiday for May 3rd, creating an extended holiday sequence that keeps Golden Week in full swing. Most retail stores, restaurants, and entertainment venues remain open. Hiking trails and mountain areas are crowded with recreational visitors.
