Kamakura home

Here is my son's new home in Kamakura for the next 3 years that he will be working for the Navy in Yukosuka.
Here is a tree planted and a small space where the kids plan to put in a tiny garden

Below is our only worry.  Kind of a steep bank at the back of their house that goes up a long way.  It is help by some mesh up to the foilage, but when a typhoon hits and if the bank gave way?  But the night we stayed there there was terrible rain and nothing slid down so probably okay.
