Byoudouin 平等院 is another World Heritage temple in Japan (they have so many). Situated in Uji, the most striking feature is the big red doors at the entrance. Its Phoenix Hall, a national treasure, is built in the middle of a pond, like an island. It had guided tours, but we didn’t join.
There was also an underground museum on the complex, and here was one of the weirdest things in Japan. The museum was strongly air conditioned, and the glass front door was left open! We felt the cool air about 10m away from the entrance, even though it was 36 degrees that day. Maybe if they kept the door closed here, then they could afford to cool some of their shopping malls and still be ‘eco’.
