The photos taken at Nijo-jo Castle in Kyoto during my visit in February 2018.

From Wikipedia:

In 1601, Tokugawa Ieyasu, the founder of the Tokugawa shogunate, ordered all the feudal lords in western Japan to contribute to the construction of Nijō Castle, which was completed during the reign of Tokugawa Iemitsu in 1626. While the castle was being built, a portion of land from the partially abandoned Shinsenen Garden (located south) was absorbed, and its abundant water was used in the castle gardens and ponds. Parts of Fushimi Castle, such as the main tower and the karamon, were moved here in 1625–26. Nijo Castle was built as the Kyoto residence of the Tokugawa shōguns. The Tokugawa shogunate used Edo as the capital city, but Kyoto continued to be the home of the Imperial Court. Kyoto Imperial Palace is located north-east of Nijō Castle. 

The central keep, or tenshu, was struck by lightning and burned to the ground in 1750. In 1788, the Inner Ward was destroyed by a citywide fire. The site remained empty until it was replaced by a prince’s residence transferred from the Kyoto Imperial Palace in 1893. 

In 1867, the Ninomaru Palace, in the Outer Ward, was the stage for the declaration by Tokugawa Yoshinobu, returning the authority to the Imperial Court. In 1868 the Imperial Cabinet was installed in the castle. The palace became imperial property and was declared a detached palace. During this time, the Tokugawa hollyhock crest was removed wherever possible and replaced with the imperial chrysanthemum. 

In 1939, the palace was donated to the city of Kyoto and opened to the public the following year. In the 21st century, typhoons have periodically caused sections of plaster to peel off the walls after exposure to rain and wind.
