The longest stretch of public holidays in Japan, the annual Golden Week happens at the end of April through early May. It’s made up of four special days: Showa Day (April 29), Constitution Day (May 3), Greenery Day (May 4) and Children’s Day (May 5).

Greenery Day was originally gazetted as a celebration of Emperor Showa’s (1901 to 1989) birthday. It was later renamed Greenery Day, and as its name suggests, this is a day to appreciate nature and relish in the great outdoors.

Better yet, on this day, many of Tokyo’s top nature attractions, such as parks and gardens including a zoo and an aquarium, will be offering free entry. So slap on some sunscreen – we’re going out to these lush green attractions in Tokyo on Sunday May 4 2025. It’s one of the best days of the year to explore Tokyo for free.
