Greenery Day 2026 in Japan

Greenery Day, observed on May 4, celebrates nature, the environment, and gratitude for the blessings of the natural world. It encourages people to spend time outdoors and appreciate Japan's rich natural beauty.

Greenery Day: A Public Holiday?

Greenery Day (Midori no Hi) is a national public holiday in Japan, when schools, offices, and most businesses close as people take time to enjoy nature and reflect on the importance of environmental harmony.

Greenery Day

Greenery Day, known as Midori no Hi, was created to show appreciation for nature and the environment. Its roots are connected to Emperor Showa (Hirohito), who had a deep love for plants and natural science. During his reign, April 29 was celebrated as his birthday. After his death in 1989, this date was renamed Greenery Day to honor his legacy without directly referencing his name, due to the complex memories of World War II.

In 2007, the Japanese government made changes to the holiday calendar. April 29 became Showa Day, specifically honoring the Showa era, while Greenery Day was moved to May 4. This adjustment allowed the message of environmental appreciation to continue while also respecting historical transitions. Greenery Day is now part of Golden Week, one of Japan's longest holiday periods. It has evolved from an imperial remembrance into a day that encourages everyone to enjoy nature and reflect on the importance of protecting the environment.

Greenery Day is celebrated quietly and peacefully across Japan. Many people take advantage of the holiday to spend time outdoors with family and friends. Parks, gardens, and nature trails are popular spots where people enjoy the fresh air, blooming flowers, and green landscapes. Since the day is about honoring nature, it is common for families to go on picnics, take walks, or simply relax under the trees. The timing in early May also brings pleasant weather, making outdoor activities especially enjoyable.

Cities and local governments often organize eco-friendly events, including tree planting ceremonies, environmental workshops, and clean-up drives. Some botanical gardens and zoos offer free or discounted entry to encourage more people to connect with nature.

Greenery Day is important because it reminds people to appreciate the natural beauty around them and to be mindful of how their actions affect the environment. It encourages a pause from the fast pace of everyday life and invites reflection on the harmony between people and nature. The holiday also reflects traditional Japanese values of living in balance with the earth. As part of Golden Week, it allows families and communities to spend meaningful time together outdoors.
