This is an official from Taiwan but the card is actually from Japan, it shows the Matsuyama Castle.
Matsuyama Castle is one of Japan's twelve "original castles", i.e. castles which have survived the post-feudal era since 1868 intact. It is also one of the most complex and interesting castles in the country. It is located on Mount Katsuyama, a steep hill in the city center that provides visitors with a bird's eye view of Matsuyama and the Seto Inland Sea. There are about 200 cherry trees on the castle grounds, making this a lovely cherry blossom spot typically around late March to early April each year.
Matsuyama Castle was constructed between 1602 and 1628. In 1635, the castle got assigned to a branch of the Matsudaira family, relatives of the nation ruling Tokugawa, and it remained in their hands until the end of the feudal era. The current three storied castle tower was constructed in 1820 after the original five storied one had been destroyed by lightning.
Matsuyama Castle provides an excellent example of a feudal castle. The main circle of defense (Honmaru) is located on the top of the hill, accessible through multiple, well defended gates. The main keep is one of only a few in the country that boast multiple wings. The complex also includes a secondary keep and multiple turrets, giving Matsuyama Castle a grand appearance and making it interesting to explore. Inside the castle, some exhibits offer information on Matsuyama's history and the feudal period. - in: http://www.japan-guide.com/e/e5501.html
