This is the Osaka Castle in Osaka, Japan. Which is one of the most important landmarks in Japan, due to the fact that it played a significant role in the sixteenth century for unification. 

Osaka Castle was built by Toyotomi Hideyoshi in 1583, it overs about 15 acres. It is based on two raised stages of landfill held by sheer dividers of cut rock, utilizing a strategy called Burdock heaping, overlooking a moat. A moat is a deep ditch filled with water that are usually around castles, buildings or towns used as a line of defense, to make it harder for enemies to get in. 

The plan for the Castle was based on Azuchi Castle, which was the headquarters of Oda Nobunaga. 

Toyotomi wanted to build a castle that mirrored Oda's but was better in every way. In 1585, the inner donjon was completed and Toyotomi continued to expand the castle. In 1597, Toyotomi died and passed it onto his son, Toyotomi Hideyori. 

After the Osaka Castle fell to Tokugawa in 1615, it was re-armed and remodeled under the power of Tokugawa Hidetada. The walls built in the 1620s are still standing currently and are made out of interlocked granite. 

In 1868, the Osaka Castle fell and was surrendered to imperial loyalists. Most of the castle was burned in the civil conflicts of the Meiji Restoration.
