Place of the first kick


I visited Shimogammo Shrine for the first time in a while. I usually go straight back along the approach to the shrine from Tadasu-no-mori forest, but I went through the horse stable located right next to the shrine. This is where the horseback archery event "Yabusame" is held on May 3.


Walking through the fresh greenery, I spotted something strange at a small shrine!


A big Rugby ball!

This Sadawasha Shrine is widely revered as a rugby shrine!


Here in Tadasunomori, Keio University students taught rugby to Kyoto University students in 1910, which was the beginning of Kansai rugby. I forgot to take a crucial photo, but there was a stone monument "the place of the first kick" standing next to the shrine.
The history of Japanese Rugby was engraved in such a familiar place.

Cherry blossoms in full bloom in Kyoto

The cherry blossoms were in full bloom in Kyoto City, and since the temperature did not rise much after the blooming was declared, I was able to enjoy them for an unexpectedly long time.
