Nioh 3 Complete Walkthrough: Every Mission, Every Secret, Zero Spoilers
I'm going to walk you through Nioh 3's structure without spoiling the story beats, because the time travel narrative is genuinely good and knowing the twists ahead of time would ruin it. Takechiyo's journey through four eras of Japanese history has some moments that hit hard if you go in blind. This guide focuses on routing, not plot.
Sengoku Era (Missions 1-4)
You start in the Warring States period, the classic samurai setting most players expect from the Nioh franchise. The first four missions teach you the basics: combat fundamentals, the open region structure, how shrines work, and how time travel gates unlock new areas.
Mission 1 is a linear dungeon through a burning castle. It's forgiving by design. The boss at the end, the Daiyokai I covered in the boss guide, is your first real test. Before entering the boss room, explore the side path to the left. There's a hidden blacksmith anvil that lets you upgrade your weapon one tier early. Most players walk right past it because the objective marker points forward.
Mission 2 opens the first open region. This is where the game expects you to wander. The map has question marks for undiscovered locations. Clear all of them before progressing the main story. Each one rewards a weapon, armor piece, or Guardian Spirit fragment. If you skip them, you'll be undergeared for mission 3.
The Corrupted Shogun at the end of mission 3 is the Sengoku era's difficulty spike. My boss guide covers the specifics. Before you go in, make sure your weapon is at least plus 3 from the blacksmith. If it's not, farm the camps around the shrine nearest the boss arena until you have enough materials.
Mission 4 closes the Sengoku arc. You'll unlock Kusanagi as a permanent Guardian Spirit after completion. Don't skip the optional duel against a wandering swordsman in the bamboo forest on the east side of the map. Beating him unlocks the Iai Quickdraw skill tree for katana users. If you're not using katana, do it anyway because he drops a crafting material used in every build's endgame weapon.
Heian Era (Missions 5-8)
The time jump to the Heian period changes the visual palette completely. Gone are the war-torn villages. Instead you get imperial court gardens, misty mountain temples, and a lot of supernatural Yokai activity. Enemies here use more elemental attacks than the Sengoku era, so start paying attention to elemental resistances on your armor.
Mission 5 introduces the Shinobi combat style's traversal abilities. There's a rooftop section that you can't complete without switching to Shinobi style for the double jump. The game doesn't tell you this. I spent 20 minutes trying to find a ladder that doesn't exist.
Mission 6 has the Court Noble of Shadows boss. Already covered. Go in with fire damage or suffer.
Mission 7 is the longest in the game. It spans a mountain temple complex with three separate boss encounters, two of which are optional. Do the optional ones. One drops the full Spirit Channeler armor set piece early, and having even one piece of that set makes the next mission noticeably easier.
The Giant Onryoki at the end of mission 8 closes the Heian arc. After this fight, the blacksmith unlocks the ability to transfer set bonuses between gear pieces. This is a game-changing upgrade that the game barely mentions. Visit the blacksmith immediately after mission 8 and learn how this system works. It's the difference between struggling through the endgame and cruising.
Bakumatsu Era (Missions 9-12)
The late Edo period, late 1800s. Guns are now a thing. You'll face enemies with rifles who can chunk your health from across the arena. The counterplay is simple: close distance fast. Every rifle enemy has a long reload animation. Sprint at them the moment they fire and you'll reach them before the next shot.
Mission 9 is a Western-style fortress. The Rifle Yokai Commander boss is a pushover if you rush him, a nightmare if you try to fight at range. Just run at him.
Mission 11 introduces the Crucible mechanic's story justification, though the actual Crucible content doesn't unlock until post-game. Pay attention to the lore here if you care about why the endgame exists. If not, just know that this mission drops the best katana in the main story from a chest hidden behind a waterfall in the mission's second half.
The War Machine in mission 12 is the Bakumatsu wall. I've covered strategies elsewhere. If you're still running a physical build, this is where you'll question your life choices.
Edo Era (Missions 13-16)
The final arc. More traditional samurai aesthetics return, but with endgame enemy density. Missions 13 through 15 are a gauntlet of high-level Yokai and human duelists. You'll want your build finalized by mission 14 because the game stops giving you breathing room to experiment.
Mission 15 has the best farming spot in the main game: a shrine right next to an enemy camp that spawns three high-tier Yokai. They drop Amrita at roughly triple the rate of any previous camp. Farm this for an hour and you'll gain 15 levels. It makes the final boss much less punishing.
Mission 16 is the final confrontation with Kunimatsu. Three phases, covered in the boss guides. Before entering, upgrade every piece of gear you own to max. Use every crafting material you've been hoarding. There's no reason to save them. The post-game Crucible drops better materials than anything you've found in the story, so the stockpile you've been sitting on becomes obsolete the moment you clear the credits.
After the credits roll, the Crucible unlocks. That's an entirely separate challenge with its own progression. But for the main story, following this route order and hitting the key upgrades when I mentioned them should get you through all 16 missions without ever feeling truly stuck. The game is hard, but it's fair. Except that War Machine. That thing is just mean. I don't know what Team Ninja was thinking with that one.
