On the Day with a Buddhist Ritual

At the head temple of Koyasan Shingon Buddhism, Kongobuji, the special decoration is done along the approach to the front and side gates on special days in Buddhism.

Classical wooden pails are lined up on both side of the approach and neat piles of Japanese cedar branches are placed by the gate. They are said to be used as drinking water and the grass for the horses who brought their masters to the temple.
The red tubs by the gate are said to be used for those masters purified their hands before entering the temple.

It was HANAMATSURI, the Flower Festival to celebrate the Buddha(Shakyamuni)'s birthday today.
