2020年2月7日 岡山後楽園の恒例行事「芝焼き」の様子です。

This event began in 1965, and it effectively gets rid of pests just as new growth is appearing in the spring.
The brown grass goes up in flames and chars to black, making for one of Korakuen’s early spring traditions.

History of Koraku Garden
In 1687, Ikeda Tsunamasa, daimyo (feudal lord) ordered his vassal Tsuda Nagatada to begin construction of Okayama Korakuen. It was completed in 1700, and it has retained its original appearance from the Edo Period up to the present day, except for a few changes by various daimyo. Korakuen is one of the few Daimyo gardens in the provinces where historical change can be observed, thanks to the many Edo Period paintings and Ikeda Family records and documents left behind.(from official HP)
