Onimusha: Way Of The Sword doesn't have a huge open world, but it still has its fair share of collectible items and treasure. Normally, the game will just tell you where everything is, and even give you a guiding light to lead you there. However, there are a few exceptions to this and one of them is the Hidden Treasure Location quests. In total, there are five Hidden Treasure quests in Onimusha: Way Of The Sword. To save you the trouble of pinpointing where the treasures are, we made this guide. The first hidden is hidden on the second roof on the house south-east of the Spirit Mirror: Kiyomizu-zaka Slope. Go around the building and climb the two sets of ladders. The treasure is on the right side of the room (from the second ladder). Very easy to find. This one was quite tricky for us. The image shows a ladder and a stone wall, but there were quite a few in the area. You're supposed to follow the river to reach this point, but that just ended up confusing us. We skirted around the edges of the zone and eventually found it in the northern part of the highlighted zone. This one isn't difficult at all, but ended up confusing us for no apparent reason. The image shows a temple door, and so we wasted our time near the entrance. Little did we know, these temples have 3 or 4 doors, and most of them are locked. The hidden treasure is right in front of the inner side of the eastern door. You'll likely need to defeat a bunch of Genma to get here. Easier than it seems. The image shows a terrace of a wooden house, but the area is covered in Malice. So, it's just a matter of finding an intact wooden house. After you enter the area (and wall run over the broken bridge), take the left path that leads up the hill. The house is in the very northern part of the area, after you climb the ladder. The treasure is just on the other side of the terrace. Another easy one, that we couldn't figure out, for some reason. Once you enter the temple right next to the Yasaka Pagoda Spirit Mirror, turn left and enter the watchtower. Use the ladders inside and climb all the way up. The treasure is on the roof. There you have it. Enjoy your upgrades.
