By Ambar Jimenez | 2025-03-22 15:54:30
Katano Castle, located in the Izumi Settsu region of Assassin’s Creed Shadows, is one of the first heavily fortified locations players will encounter. This imposing fortress is not only a test of your combat and stealth skills but also a treasure trove of valuable loot and hidden secrets. Among its many challenges, one of the most intriguing is the locked door on the ground floor of the castle. While the primary objectives of defeating all Samurai Daisho and looting the chest are straightforward, the locked door presents a puzzle that requires a bit of exploration and strategy to solve. In this guide, we’ll delve into the details of how to unlock the door and claim the rewards hidden within.

The Mystery of the Locked Door


As you explore Katano Castle, you’ll likely come across a locked door on the ground floor. Using Naoe’s Observe skill, you’ll notice several chests and valuable loot behind it. However, the game provides no immediate clues on how to open it. The message simply states that the door is locked, leaving players to figure out the next steps on their own.
The solution lies in finding a hidden key within the castle grounds. This key, known as the Katano Castle Kura Key, is tucked away in a specific location, and obtaining it requires careful navigation and combat strategy. Below, we’ll walk you through the process step by step.

Step 1: Locating the Katano Castle Kura Key


The key to unlocking the door is hidden in a house located in the northeast section of the castle grounds. To reach it, you’ll need to navigate through a courtyard patrolled by a Samurai Daisho, several guards, and two orderlies. This area is heavily guarded, so stealth and patience are essential.
  • Approach the Northeast Courtyard: Make your way to the northeastern part of the castle grounds. You’ll find a house surrounded by enemies. The key is inside this house, but getting to it won’t be easy.
  • Deal with the Enemies: Before attempting to enter the house, it’s wise to clear out as many enemies as possible. Use stealth to take down guards one by one, avoiding detection. Be cautious of the two high-level enemies in the room on the east side of the house—these foes are best avoided unless you’re confident in your combat abilities.
  • Enter the House: Once the area is relatively clear, head to the south side of the house and enter through the door. Be prepared to face a guard inside the room. Dispatch them quickly to avoid raising an alarm.
  • Find the Key: Inside the house, the Katano Castle Kura Key is located on a table in the westernmost portion of the room. Grab it, and you’re one step closer to unlocking the mysterious door.
  • Step 2: Unlocking the Storage Room (Optional)


    Before heading back to the main castle, you can take advantage of the key to unlock a storage room located just south of the house where you found the key. This roomcontains additional loot, making it a worthwhile detour. Open thestorage room to claim your rewards and stock up on resources.

    Step 3: Returning to the Main Castle


    With the Katano Castle Kura Key in hand, it’s time to return to the main castle. The locked door is located on the west side of the ground floor, near the entrance. Here’s how to get there:


  • Navigate to the Main Castle: Head to the southwest section of the compound. If you’ve already unlocked the front gate, you can enter directly. Alternatively, you can use the trapdoor on the roof to access the interior.
  • Locate the Locked Door: Once inside the main castle, the locked door is on the right side (west) as you enter through the main gate. Approach the door and use the Katano Castle Kura Key to unlock it.
  • Step 4: Claiming Your Rewards


    Behind the locked door, you’ll find a room filled with valuable resources and a unique weapon. Here’s what awaits you:


    • Resource Stockpiles: These contain essential crafting materials and supplies to aid you on your journey.
    • x5 Minerals: Valuable items that can be used for upgrades or traded.
    • Clandestine Tanto of Stealth: A powerful dagger that enhances your stealth capabilities, making it a valuable addition to your arsenal.

    Tips for Success


    • Use Stealth: The castle is heavily guarded, and engaging in open combat can quicklyoverwhelm you. Use Naoe’s stealth abilities to silently eliminateenemies and avoid detection.
    • Plan Your Approach: Take time to observe enemy patrol patterns and plan your route to thekey. Rushing in blindly can lead to unnecessary confrontations.
    • Upgrade Your Gear: Before tackling Katano Castle, ensure your weapons and armor areupgraded. This will make combat encounters easier and give you an edgeagainst high-level enemies.
