The Oshoin was the second enclosure of Sasayama Castle for 335 years until it was destroyed by fire in 1944. It has now been reconstructed, the product of much scholarly research and craftsmanship, and recreated down to the ancient building techniques and exquisite decoration.
For example, two different but elegant techniques have been used in constructing the roof of the Museum, and the beautiful sloping roof that is the symbol of the Oshoin. About 4 years were spent on completing the Oshoin, and if you look closely you can see that every detail has been given consideration.
The sight of the elegant form of the Oshoin during cherry blossom season in spring, summer fireworks, red leaves in fall and snow in winter brings to mind the former glories of the castle in her heyday in the 17th century and across the ages.
