Our guide
Mihara Castle was a flatland castle in what is now the city of Mihara, Hiroshima. Its ruins have been a National Historic Site since 1957. Our source says little more than that, so this page is short.
Mihara Station on the San'yō Main Line is only about 100 m away in a straight line. We have not checked what can be seen on the site today.
