What Are Samurai and Ninja Locks? 🎯
Samurai and Ninja Locks are key items in Nioh 3 enabling progression in combat styles. Without them, you cannot unlock advanced abilities and techniques.
Why they’re important:
✓ Unlock Martial Arts (samurai techniques)
✓ Provide access to Ninjutsu abilities
✓ Allow learning new weapon attacks
✓ Each weapon has its own skill tree
✓ Critical for optimal builds
You might be wondering: What’s the difference between Samurai and Ninja Locks? Samurai Locks unlock martial arts and melee techniques, while Ninja Locks provide stealth abilities, tools, and quick attacks.
All Methods to Obtain Locks 📋
1. Missions and Myths (Quests) 🗺️

Primary source of locks in Nioh 3:
| Quest Type | Reward | Difficulty |
|---|---|---|
| Main missions | Often both types | Medium-High |
| Side myths | Specific locks | Low-Medium |
| Story quests | Guaranteed locks | Various |
How they work:
- Quests trigger during map exploration
- Completion automatically rewards locks
- Some myths give specifically Samurai or Ninja locks
💡 Pro tip: Monitor the map for quest icons. Almost every myth rewards at least one type of lock, so complete all side quests for maximum gain.
2. Looting Bodies 💀
Dead bodies scattered across the map often contain valuable items:
Where to look:
✓ Near powerful enemies – higher chance for locks
✓ Hidden areas – often better loot
✓ Boss arenas – check surroundings after battle
✓ Dangerous locations – risk = reward

❌ Common mistake: Ignoring bodies in regular areas. Even standard locations can contain locks – check every body you find.
3. Scampuss and Chijiko Yokai 🐱


Friendly yokai sometimes drop locks after interaction:
Scampuss (cat-like yokai):
- Find Scampuss during exploration
- Follow it until it stops running
- Pet it when it stops
- Chance for Samurai or Ninja Lock
Chijiko (flying yokai):
- Spot Chijiko in the air
- Shoot it down with projectile weapon
- Pet after landing
- Possible lock drop
💡 Pro tip: Scampuss requires patience – don’t rush. Chijiko are easier – use bow or ninja stars for quick takedown.
4. Chests and Containers 📦

Chests throughout the map contain various items:
Chest types:
- Standard – occasional locks
- Locked – higher chance for rare items
- Hidden – often better rewards
- Mimics – dangerous but lucrative
⚠️ Warning: Some chests are Mimics – enemies disguised as chests. Be prepared for combat.
5. Exploration Level 🌟

Increasing Exploration Level of a region rewards locks:
| Level | Reward | Requirement |
|---|---|---|
| 1 | Basic items | 25% exploration |
| 2 | Possible locks | 50% exploration |
