FindYourStampsValue.com would like to introduce the third issue of Japanese Castle Series to introduce remaining castles all over Japan. This philatelic release consists of five stamps that were put into circulation on the 10th of December.
Japanese castles were fortresses constructed primarily of wood and stone. They evolved from the wooden stockades of earlier centuries, and came into their best-known form in the 16th century. Castles in Japan were built to guard important or strategic sites, such as ports, river crossings, or crossroads, and almost always incorporated the landscape into their defense.
Though they were built to last and used more stone in their construction than most Japanese buildings, castles were still constructed primarily of wood, and many were destroyed over the years. This was especially true during the Sengoku (Warring States) period (1467–1603), when many of these castles were first built. However, many were rebuilt, either later in the Sengoku period, in the Edo period (1603–1867) that followed, or more recently, as national heritage sites or museums.
Today there are more than one hundred castles extant, or partially extant, in Japan; it is estimated that once there were five thousand. Some castles, such as the ones at Matsue and Kōchi, both built in 1611, remain extant in their original forms, not having suffered any damage from sieges or other threats. Hiroshima Castle, on the opposite end of the spectrum, was destroyed in the atomic bombing, and was rebuilt in 1958 as a museum.
