The dark keep, entered through its attached turret
- Where
- The keep in the honmaru (main enclosure), with its entrance turret projecting to the south.
- What to look at
- The black wooden siding, the attached turret (tsuke-yagura) that guards the door, and the stone-drop openings on the second floor.
- Why it's interesting
- This is a composite keep: a separate turret is attached, and you can only enter the keep through it, which made it harder for attackers to get in. Completed around 1611, it is one of only 12 original keeps left in Japan and a National Treasure, alongside keeps such as Hikone and Himeji.[1][14]
- Can you see it?
- Visible from outsideThe exterior is visible from the honmaru (free; open during gate hours). Entry to the keep is paid.
