Background & Origins
A Celebration of Nature
Greenery Day in Japan is called みどりの日 (Midori no Hi), and it is celebrated on May 4 every year.
This holiday is a day to appreciate nature, plants, and the environment. It encourages people to notice the beauty of the natural world and to think about the connection between human life and nature.
Greenery Day is also connected to Emperor Shōwa (昭和天皇 / Shōwa Tennō), who was known for his interest in plants and biology. After his death, the holiday system changed several times, and Greenery Day was officially moved to May 4 in 2007.
May 4 is one of the national holidays during Golden Week, one of the busiest holiday seasons in Japan. Because it falls between other holidays, many people already have time off, so it becomes a chance not only to rest, but also to enjoy the season of fresh green leaves, flowers, and mild spring weather.
For Japanese learners, the name of this holiday is also interesting. The word みどり (緑, midori) means “greenery” or “green plants,” so the holiday’s name directly reflects its theme.

What do people do on this day?
Greenery Day as Part of Golden Week
Because Greenery Day is part of Golden Week, many people spend it traveling, relaxing, or meeting family and friends. Some take short trips to the countryside, while others stay in the city and enjoy local parks or gardens.
Since the holiday is about nature, it is also common for people to do outdoor activities. For example, they may:
- visit parks or botanical gardens
- go hiking or camping
- have a picnic with family
- enjoy flower viewing or fresh spring scenery
- join local environmental or community events
For some people, Greenery Day is not about doing something formal. It can simply mean slowing down and enjoying the natural world around them. Even a walk under green trees or time spent in a nearby garden can feel special.
Because early May is usually a pleasant season in Japan, this holiday matches the weather very well. Trees are full of fresh leaves, the air is comfortable, and many people want to spend time outside.
Some museums, zoos, gardens, or public facilities may also hold special events or offer free admission around this time. That makes Greenery Day a good chance for families with children to go out together and learn something new.

Greenery Day and Golden Week
Golden Week is a group of national holidays at the end of April and the beginning of May. Because several holidays are close together, many people take vacations during this period.
Greenery Day is one of the important holidays in this week, along with holidays such as:
- Showa Day (昭和の日 / Shōwa no Hi) on April 29
- Constitution Memorial Day (憲法記念日 / Kenpō Kinenbi) on May 3
- Children’s Day (こどもの日 / Kodomo no Hi) on May 5
This means Greenery Day is often experienced as part of a longer holiday rhythm. People may travel on one day, rest on another, and spend May 4 outdoors enjoying spring.
