Hakone Retreat Villa1/f
Sengokuhara, Japan
These detached villas make the most of Sengokuhara’s wooded setting, with natural materials, generous windows and private hot-spring bathing. They belong to a wider retreat with dining, a café and shared facilities, so seclusion need not mean staying entirely in your room. Choose the villa accommodation specifically when reserving, since the property also has a separate hotel called före. This is a good base for a quiet stay punctuated by visits to nearby museums.
