Time flies. June 30th is the last day of the first half of the year. And in Japan there is a unique custom held in many Shinto shrines. (Shinto is the indiginous religion of Japan.)
A big circle made by pampas grass is placed in the Shinto shrines. People pass through the circle to wish for purification and coming good luck.
I took these pictures at Heian Shrine. You can see the big circle placed at the gate. The red architecure covered with a green roof was modeled after Emperor's palace of the 11th -12th century in 5/8th scale.
