I would like to call it good planning but it was just shear coincidence that we were heading to Yoyogi Park for a walk and the area was full of fully activity. We knew it was a public holiday but were pretty surprised to see such a big crowd at the Shrine until we worked out it was actually Japan's National day or Kigen-Sai. I think it is all about celebrating when the Emperor first sat on the throne and Japan was formed as a nation. I felt we were pretty lucky to be able to visit on such a special day.
