Greenery Day is a public holiday in Japan celebrated on April 29. It was established to promote an appreciation for nature and the environment. Originally, it was part of the Golden Week, a series of holidays that includes Showa Day and Constitution Memorial Day. The day encourages people to enjoy the outdoors and participate in activities that foster a connection with nature. The holiday was first celebrated in 1989, following the death of Emperor Showa, who was known for his love of plants and nature. In 2007, the date was moved to April 29 to honor the birthday of Emperor Showa, also known as Hirohito. Greenery Day is a time for reflection and appreciation of the natural world.
