Kanbara (or Kambara), the 15th post town from Edo along the old Tokaido Highway, retains some of its original atmosphere due to a collection of historical buildings that still remain intact. Originally a ryokan, the 180 year old Izumiya is now a combination of cafe, local goods & crafts shop, and a place where locals can practice traditional weaving techniques.
While in the area, be sure to visit, and tour, two local homes that have turned into museums. The Shida Residence and the former Igarashi Dental Clinic.
