Are you wondering how to open the door of the house near the Tenryu River? Well, you’ll have to find a particular key, but first, you’ll need to deal with certain enemies who might not be easy to defeat. In this guide, we’ve outlined everything you need to know to get the Dirty Key from the enemy, open the locked door, and get the collectibles without any hassle.
How to Use the Dirty Key to Open the Door


Once you go to the Chijiko region, which is near the Tenryu River, you’ll find a house with a locked door. To open the door, head toward the small cluster of huts in the distance. From there, go straight, and into the middle of the village. You’ll need to get on top of the roof and defeat the enemies so that they don’t cause trouble afterwards.

Once the enemies on the rooftops are dealt with, get down, and you’ll see that there’s a wolf yokai named Yamainu patrolling the area. You’ll need to defeat him to acquire the Dirty Key. After getting the key, go up the hill and back to the house with the locked door. Use the Dirty Key to unlock it and go inside. You’ll find a chest filled with collectibles that’ll be of help to you.
