What this place is
Odani Castle (小谷城, Odani-jō) was a Sengoku period mountain-top Japanese castle located in the former town of Kohoku, now part of Nagahama city, in Shiga Prefecture, Japan. Only the ruins remain today. It was the home castle of the Azai clan and the mountain it was built upon was considered to be impregnable. The castle fell during Oda Nobunaga's siege in the Genki and Tenshō eras (Siege of Odani Castle), in 1573. Its ruins have been protected as a National Historic Site since 2005.

Why it is worth the trip
- Massive dry-stone walls and moats built without mortar — the engineering is as impressive as the tower above it.
- A main keep (tenshu) you can climb, with each floor showing armour, weapons and castle-town models.
- Grounds that double as the town's best park: cherry blossoms in spring, maples in autumn, illumination at night.
What you can do here
- Climb to the top floor for a 360° view over the castle town and surrounding mountains.
- Walk the full circuit of the moat and outer baileys — the gates and turrets are free to see from outside.
- Rent a kimono or samurai costume nearby for photos in front of the keep.
- Time your visit with a seasonal festival or evening light-up, when the walls are lit from below.
