Quick Links
Assassin’s Creed Shadowsis full of castles, forts, and fortresses that are spread across the vast regions of Japan, hidden in the mountains, or visible in the center of town. While some locations are necessary to visit as part of the main story or other major side quests, other castles are completely optional, leaving you the choice to plunder their legendary loot or not.
Since you’re here, the allure of legendary loot in Kashiwabara Fortress was likely too much for you to resist, especially with only a lone Samurai Daisho to defeat. Each area guarded by Samurai Daisho boasts a Legendary Chest that can only be opened once all Daisho are defeated, making this one of the easiest sources of legendary gear in Assassin’s Creed Shadows.

Where Is Kashiwabara Fortress?
The Kashiwabara Fortressis located far in thenortheasternsection of the map in theIbu Highlandssection ofOmi.You can approach from the north, west, or south, with the nearest fast travel point being theNagahama Kakuregato the west.
This is one of the shortest fortresses in Assassin’s Creed Shadows withonly a single Samurai Daisho to slaybefore you can set your sights on the Legendary Chest.

Given the small area and lack of targets to hunt down, the Kashiwabara Fortress gives you the best value for your time if you want to hunt Legendary Gear.
How To Find And Assassinate The Samurai Daisho
You’ll find thelone Samurai Daishoin the directcenterof the Fortress, patrolling theeastern courtyard.
The first strategy involves careful play and can be risky. Skip to the alternative silent assassination if you’d rather be careful.

The fastest way to killyour target silently is by climbing the ladder and ambushing the Daisho from thetower on the eastern sideby luring them over with aShinobi Bell.You can also let yourself be seen for a moment, then retreat to the safety of the tower, but this might alert the Daisho.
Alternatively,you can take the long way to the opposite side of the courtyard bycircling the right sideuntil you’re just above the Samurai Daisho, at which point you can air assassinate him.

This is much safer but takes slightly longer.
