Kokura Castle is a symbol of Kokura built from the end of the 16th century to the early 17th century. The castle tower is called a "kara-zukuri castle tower" because there is no roof knee between the 4th and 5th floors, and the 5th floor is larger than the 4th floor. In addition, the stone walls of the castle are a natural grass without cut stones. You can experience its unique and exciting atmosphere. From the 5th floor on the top floor, take in great views of Kokura city.

This pond style garden sits on the site of the old mansion of Ogasawara, on the east side of Kokura Castle. In the House of Manner and Etiquette, enjoy matcha (sencha) and seasonal sweets served in the tatami room. In the garden, you can enjoy the scenery while walking around the "Nozoki Pond" beside the mansion.
