Katano Castle stands as one of the first major fortresses you will encounter in Assassin’s Creed Shadows.
Located in the Izumi Settsu, the imposing structure hides the treasures behind the doors that are locked and protected by specific keys.
How To Find The Katano Castle Kura Key?
To find Katano Castle Kura Key, go into the northeastern section-most corner of the castle grounds into a house. Look for a house with a tightrope.
Before you try to get the key, take out the enemy by the house so as not to be seen. The key is on a table at the westernmost part of the house.

This location is very problematic because you will be up against:
- A Samurai Daisho
- Multiple guards
- 2 orderlies
To go in stealthily, eliminate as many enemies as possible before entering through the back door south of the house. Be careful of a guard in the room to avoid being spotted by him, which would alert more enemies.
The room also has two enemies of a higher level on the eastern side, and the last thing you want to do is engage them if you’re not in the mood for a real fight.
What Does The Kura Key Unlock?
The Katano Castle Kura Key opens two big prizes:
1. Storage Shed Near The Key Location
Just after getting the key, one can unlock a storage shed a few feet from the house where the key was. This barn has a bunch of goodies that will stock up your inventory.
2. Storage Room Behind Locked Doors in the Main Castle Tower
The primary location of the locked door is on the ground floor of the main castle tower, which is entered through:
- The main gate, if open
- If the main gate is not open yet, then through the trap door from the roof
- Find the locked door on the west side after you’ve entered through the main gate
Using Kura Key here gives access to:
- Several resource stockpiles
- 5 Minerals
- The Clandestine Tanto of Stealth.
Additional Katano Castle Rewards
While exploring Katano Castle, here are some other exquisite opportunities you shouldn’t miss:
Legendary Chest
The legendary chest is on the middle floor of the main castle tower. To get to it:
- Go up the castle
- Enter through the right-side window
- Down the stairs
- Open the door in the room on your current floor
This chest contains the Tools Master Gear, and the Kunai Throw on Assassinate ability. Expect enemies on this floor.
Samurai Daisho Locations
For a clean clearing of Katano Castle, you must kill both Samurai Daishos;
- The first patrols the northeastern corner of the castle
- The second is east of the main castle tower

Katano Castle represents just one of several fortresses in the Izumi Settsu region. Mastering its layout and discovering the Kura Key will prepare you for the more challenging castles that await in your Assassin’s Creed Shadows journey.
