Completion Guides Reveal All Hidden Treasure Locations in Onimusha: Way of the Sword

New comprehensive guides have been released detailing the locations of hidden treasures and collectibles in Capcom's action game Onimusha: Way of the Sword. These resources provide a roadmap for players navigating the game's challenging environments to secure essential gear and achieve full completion.

The game features a dedicated 'Hidden Treasure' side quest consisting of five specific 'Chance Encounters.' These encounters are triggered when an NPC provides the player with an 'Old Drawing'—a photograph—and an approximate map marker to guide the search.

Detailed locations for these five treasures include a rooftop near the Kiyomizu-zaka Slope Spirit Mirror (No. 1) and the base of a small waterfall near the Yasaka Pagoda Spirit Mirror (No. 2). Treasure No. 3 is tucked inside a temple near the Kamo River – East Spirit Mirror, where players must use the 'Oni Eyes' ability near a large closed door to reveal the chest. Treasure No. 4 is situated on a balcony of a small shrine-like building in the Northeast area beyond the Gojo Street – East Spirit Mirror, while Treasure No. 5 is found on the southern side of the Yasaka Pagoda's upper rooftop.

Environmental Exploration

Beyond the specific side quests, general treasures are scattered throughout the game's historical Japanese setting, including Eastern Kyoto and Kiyomizu-dera Temple. These general chests contain critical items such as 'The Two Celestials' armament and various 'Genma Notes' (Faction Notes).

To find these items, players must utilize the game's core exploration mechanics. Onimusha: Way of the Sword blends sword-fighting with puzzle-solving, requiring the use of 'Oni Eyes' and 'Oni Gauntlets' to interact with the environment and uncover objects that are otherwise invisible to the naked eye.

Impact on Gameplay

For completionists and those struggling with the game's high difficulty, these guides are vital. Many of the high-value upgrade materials and armaments are obscured by complex environmental puzzles or locked behind specific ability requirements. Obtaining these items is often the only way to sufficiently power up a character to survive the game's more punishing encounters.

Looking Ahead

While the gameplay mechanics and treasure locations are now well-documented, some logistical details remain fluid. There are currently conflicting reports regarding the game's official launch date for PS5, Xbox Series X|S, Nintendo Switch 2, and PC, with sources citing both September 4, 2026, and September 25, 2026. Players will need to monitor official Capcom channels for a definitive release window.
