In mid-November, I went to Nijo Castle (二条城) in Kyoto. Nijo Castle is a UNESCO World Heritage site as part of the Historical Monuments of Ancient Kyoto, and is protected by various Japanese designations such as being a National Treasure, and a National Special Historical site.
Nijo Castle, which was built in 1626, was where the Tokugawa Shogunate resided when they visted Kyoto. The Tokugawa Shogunate ruled Japan from 17th century to the mid-19th century, and had a huge impact on Japanese history. For example, the Sakoku period (the 200 year period in Japanese history where Japan had almost no foreign relations), which I mentioned in my post about Kobe Ijinkangai and my post about Nagasaki, was established by the Tokugawa Shogunate.
Hope you enjoyed my trip to Nijo Castle in Kyoto!
