How Oni Raider Mask Pieces first appear in gameplay
You'll encounter Oni Raiders initially during the key story mission "The Road to Ishikari Plain," notably at the Golden Foothills checkpoint. Early in this quest, you begin collecting your first Oni Raider Mask Pieces, which are dropped from these enemies after combat.

Main farming locations to accumulate Oni Raider Mask Pieces
Once Ishikari Plain is unlocked, it becomes the prime area for farming Oni Raider Mask Pieces due to a high density of Oni Raider camps. Specific spots include:
- Nishin Fishery
- Bold Kaji Forge
- Oni’s Breath Inn
- Jigoku Fortress
- Ishikari Castle
Additionally, the Ishikari Plains and surrounding wolf and fox dens also feature frequent Oni Raider spawns, providing alternative routes for collecting mask pieces. Continuous clearing of these camps and enemy respawn checkpoints allows steady farming.
How to get Oni Raider Mask Pieces step by step
Step 1
Progress through the main story to reach "The Road to Ishikari Plain" quest to start encountering Oni Raiders.

Step 2
At the Golden Foothills checkpoint during this quest, defeat Oni Raiders and loot their bodies for mask pieces. You can also unlock Ishikari Plain, then seek out Oni Raider camps in key locations like Nishin Fishery and Oni’s Breath Inn.

Step 3
Clear Oni Raider camps, collecting all dropped mask pieces after each fight.

Step 4
Return to the last checkpoint and repeat clearing camps to farm more pieces efficiently.
This method is the most reliable way to gather Oni Raider Mask Pieces for crafting and upgrades in Ghost of Yotei.
Optimizations for farming Oni Mask Pieces
Unlock the region / progress main story
You need to complete a main mission to unlock the Ishikari Plain region where Oni Raiders drop the mask pieces.
Use item/charms that boost drops
You can use charms like Bountiful Harvest or Kanayago to increase resource yields (though not confirmed that they guarantee Oni Raider Mask Pieces, but they seem to help with drop quantities).
Focus on high density enemy areas / camps
Since these drops come from Oni Raiders, targeting areas where many of them spawn (or cleared camps) is more efficient.
Complete side quests in Ishikari Plain early
Some side quests in that region specifically give you mask pieces, doing them will boost your stockpile.
During main missions
Some missions inherently drop or reward mask pieces (e.g. chest in the camp during “The Oni” mission)
To get Oni Raider Mask Pieces in Ghost of Yotei, defeat Oni Raiders mainly found in Ishikari Plain during and after the main quest "The Road to Ishikari Plain." Farm Oni Raider camps like Nishin Fishery and Oni’s Breath Inn by repeatedly clearing enemies and looting their drops. These pieces are crucial for upgrades and cannot be bought, so persistence is key. Focus on checkpoints for efficient farming and revisit areas for enemy respawns. This method ensures steady collection of Oni Raider Mask Pieces for crafting and upgrades.
