Wakayama Castle
The origin of the castle started in 1585, Hashiba Hideyoshi (later Toyotomi Hideyoshi) subjugated Kishu teritory (the area now known as Wakayama) and he ordered his younger brother, Hidenaga, to build a castle on Mt.Torafusu which is at a downstream of Kinokawa-river. Later, a vassal of the Hashiba family, Kuwayama Shigeharu was placed in charge of the castle (and later, the castle lord). After the Battle of Sekigahara, Asano Yoshinaga became lord of the castle and he started building a tower followed by an interconnected corridor. He built residences in the area now known as Honmaru, Ninomaru, and Nishinomaru while building a castle town. In 1619, Yorinobu, the 10th son of Tokugawa Ieyasu, inherited the castle.
The views are gorgeous, and the night scenery is beautiful too. The grounds aren't huge, but the staff are super friendly.
