All 7 Oni Armaments — Locations and Unlock Conditions
Published 2026-09-12Updated 2026-09-186 min read
Every Oni Armament in Onimusha: Way of the Sword: The Two Celestials, Oni Bow, Wind-Whipper, Earth-Shakers, Firebird Flute, Flashing Void and Still Water.

Oni Armaments are the campaign's special weapons, each tied to a story beat or a specific chest. None are permanently missable except by ignoring chests — here's where all seven live.
1. The Two Celestials
Where: Kiyomizu-dera Temple. How: destroy the second Thread Genma binding the second Oni Gate, then loot the chest it was tethered to. Musashi's two-sword style — you'll feel the difference immediately.
2. Oni Bow
Where: Oni Refuge (the Oni Hideout). How: a chest directly on the mandatory story path. Strictly unmissable — the game hands it over in cutscene. Your key to red orbs, distant locks and oni-eater bugs.
3. Wind-Whipper
Where: the mission "The Oni's Apprentice." How: the chest auto-generates once you've unlocked the Training Grounds and boss rematch features. If it hasn't spawned, finish that unlock first and revisit.
4. Earth-Shakers
Where: Underground Laboratory, sublevel B4. How: the chest in the room right after the fan puzzle — the descending-ceiling sequence where you shoot the four red-corded rollers. Grab it on your way out.
5. Firebird Flute
Where: the mission "Shadows Fall" — at the fissure site by the shrine on Gojo's south-east side. How: a chest at that location. Easy to sweep while clearing the area's Prison Windows.
6. Flashing Void
Where: Mount Oe, the castle courtyard. How: inside a cave you enter with a slide move. If the cave mouth looks too narrow — that's the one.
7. Still Water
Where: the Swamp of Arashiyama, map's north-east corner. How: an open-world style chest; walk up and open it. The tachi earns its keep through the endgame climb.
Collection Tips
- Prioritize the Oni Vision skills — Treasure, Treasure 2, and Search Range — before sweeping for anything.
- Build the exploration habit: hold L2/LT and tap R2/RT in every new room.
- Oni Armaments do not carry over into New Game+.
