1. Japanese Rock Walls Are Earthquake Proof
Earthquakes are common in Japan, so they have had to figure out how to earthquake-proof their structures. In some Japanese gardens, they have castle walls made from dry stacks of stone. These are held down by gravity. So if the earth shakes, the stones can adjust with the movements in the Earth.
Here in the United States, the Portland Japanese garden made their own castle walls. So if you wanted to see them for yourselves, you wouldn’t have to travel to Japan to see it. Everything in that garden is designed and maintained by actual Japanese gardeners to make it as authentic as possible to their culture. I highly recommend watching this interview on YouTube to see the full garden.
