Greenery Day in Japan

Greenery Day, known as Midori no Hi (緑の日) in Japanese, is a national holiday in Japan dedicated to appreciating nature and promoting environmental awareness. The holiday takes place on May 4th every year, as part of Japan's Golden Week—a collection of public holidays spanning from late April to early May.


Greenery Day was first celebrated in Japan on April 29, 1989, following the death of Emperor Hirohito, who had a deep love for nature and plants. Originally, April 29th was the birthday of the late Emperor and celebrated as a national holiday called "Tennō Tanjōbi" (天皇誕生日) or Emperor's Birthday. In order to honor his memory and passion for nature, the day was renamed to Greenery Day after his death.

In 2007, Greenery Day was moved to May 4th, and April 29th became known as "Shōwa Day" (昭和の日), commemorating the Shōwa era during Emperor Hirohito's reign. This change was made to maintain the theme of nature appreciation while allowing for a separate day to remember the late Emperor and the historical events of his era.

Some cities and towns also host various eco-friendly events like eco-fairs, workshops, and lectures to educate people about the importance of preserving the environment and living sustainably.
