Rain drain
Senjokaku’s draining system
A regular rain gutter would not cut it for a place like Senjokaku. For starters, the roof is massive and Miyajima gets a lot of rain.
This ingenious system turns a waterfall coming off the roof into a bedrock stream.
Unfortunately (now, for purposes of this photo, but fortunately then for purposes of my dryness), the rain had slowed by the time I took this photograph so you can’t see the water cascading off the roof so much.
