Getting to see private gardens in Japan is pretty tricky, unless you have an introduction - there’s no yellow book system of open gardens, and they’re not really geared to large numbers of people anyway. What is easy though, is looking at gardens from the road. Many Japanese homes only have a ‘front’ garden anyway, and often that is just a screen of trees, with a small enclosed area inside.
Here are two rather different approaches.
A long pine branch ( Pinus thunbergii ) trained over a Quercus phillyreoides hedge outside a treadional home.
And a contemporary look with multi-stemmed deciduous trees.
