BO7 Kowakujo Easter Egg Guide: Full Walkthrough

Black Ops 7 Zombies Kowakujo is the fifth Zombies map, dropped with Season 4 Reloaded on June 25, 2026. It's a feudal Japanese castle: Takeo Masaki's ancestral home, specifically: dragged into the Dark Aether and set on a volcano. The lava is decorative in the sense that it slows you to a crawl and turns zombies into Scorched horrors. Lovely place. The crew's goal: free the last Shadowsmith, recover the World Seed, and survive Nyxara's army of the undead. You also get a cat as a weapon.

The main quest rewards include a Purified Takeo Operator Skin, a Calling Card, and 10,000 XP. There's also a unique Calling Card variant for players who complete it before Directed Mode launches. If cosmetics motivate you more than lore, that's fine. We're all here for the same reason.

Step 1: Unlock Pack-a-Punch (World Seed)

Nothing works until you do this. The Kowakujo Pack-a-Punch is gated behind a short quest that teaches you the map's layout whether you want it to or not.

Tip: A Decoy Grenade is genuinely useful for herding marked zombies near the seed. Lava slows you down massively: avoid it while doing this step or you will die annoyed.

Step 2: Get the Nekomancer Wonder Weapon

Yes, the Nekomancer Wonder Weapon is a cat. Three abilities: Spirit Bolt, Hairball, and Neko Punch. It is also reportedly one of the most powerful Wonder Weapons the series has produced. You have to earn it through an elaborate ritual involving crafting a cat statue, PhD Flopper, and throwing that statue into lava. This is the game you purchased.

Collect three parts. Each has three random spawn locations. Check them all if one is missing: safe-quitting in solo can despawn them, forcing a respawn check.

Take all three to the Workshop. Find the crafting table near Vulture Aid and build the Maneki Neko tactical equipment. This is not the weapon yet: it's a short-range Monkey Bomb substitute used to summon the Abomination.

Part 2: Cage, Lava, Abomination, Cat

1. Buy PhD Flopper from the Storage Rooms.
2. Go to Tenshu Entrance (Mule Kick location). Look up at the SW wall: there's a cage with a cat. Dolphin-dive or wall-jump beneath it to free the cage with the explosion.
3. Pick up the cat-in-cage. Carry it to a lava zone and throw it into the lava. The cage disappears.
4. Kill zombies in four locations to trigger paw prints on the ground: Doorway from Central Courtyard to Kitchens, Doorway from Kitchens to Flower Gardens, Training Area south of the Warden 308 Wall-Buy, and one additional spot on the east side.
5. When the paw prints form a circle on the floor, wait for lava to flow across that area (happens randomly, every few rounds). Throw the Maneki Neko into the center of the circle.
6. An Abomination spawns and eats the cat. Kill it fast: it's tankier than it looks.
7. The cat reappears near creaky floorboards. Buy Death Perception from the Stables first: the highlighted boards are much easier to see. Move crouched and avoid the boards entirely. Walk up and interact with the cat.
8. Carry the cat to the World Seed (next to Pack-a-Punch in Shogun's Sanctum). The cat jumps onto the seed. Kill zombies near the seed until it pulses red. Melee the seed. The cat drops to the floor as the Nekomancer. Pick it up.

Note: If the Maneki Neko breaks (no lava nearby when you threw it), go back to the Workshop crafting table and build another one.

Step 3: Light 11 Lanterns with the Nekomancer

With the Nekomancer in hand, your next task is the lantern puzzle. Eleven lanterns are scattered across the map. Shoot each one with the Nekomancer to light it. Missing a shot or taking too long between lanterns resets the entire chain: you'll have to wait until the next round to try again.

Start from the Training Area: it requires the longest shot in the sequence. Work a logical loop back through the Stables, Staging Area, Kitchens, and Storage Rooms. When the final lantern lights and all 11 stay lit, a ghost spawns in the War Room. Approach it to advance the quest.

Recommended: Solo this step or coordinate with teammates: one missed shot by anyone fails the whole chain. Clearing a round first helps reduce distractions.

Step 4: Fox Mask, Evidence, and the Mask Wall Puzzle

After the ghost encounter, you enter the investigation phase. The Fox Mask evidence system works like a Zombies detective mini-game: collect items, bring them somewhere, and the map tells you you're good at hunting.

Get the Fox Mask via Ninja Kite

Follow the ghost's instructions after the lantern step: the Ninja Kite will be indicated by an objective marker. Interact with it to begin the Fox Mask Minigame. Completing it yields the Fox Mask.

Collect Fox Mask Evidence

Two types of evidence need collecting: Poison Evidence (Plum Pit) and Motive Evidence. Both have randomized spawn locations across the map. Check tables, shelves, and alcoves throughout the Kitchens, Tea Garden, and Flower Gardens. The objective marker will guide you once the Fox Mask step triggers.

Mask Wall Puzzle

Bring all collected evidence to the Meditation Room. Interact with the wall display to place the evidence and unlock the mask puzzle. The mask wall puzzle requires arranging masks based on clues pulled from your evidence items: each run is randomized. Read the evidence descriptions carefully. Brute-forcing it wastes time you don't have.

Three collectible key items must be acquired during or after the mask puzzle step. Each has a handful of spawn locations.

Cursed Mode: For People Who Hate Themselves

Kowakujo Cursed Mode removes all main quest guidance, limits the HUD to nearly nothing, and starts you with a pistol. In exchange you can unlock three Pack-a-Punch camos and 60,000 XP worth of cosmetic rewards. The mode also features Cursed Relics: six collectable modifiers that make the game harder in exchange for bragging rights that exist nowhere outside your own head.

• Flame Cipher Camo + Calling Card + 15,000 XP
• Toxic Cipher Camo + Calling Card + 20,000 XP
• Blood Cipher Camo + Calling Card + 25,000 XP

Complete the normal Easter Egg first. Going into Cursed blind is a personality disorder, not a strategy.

Completion Rewards

• Purified Takeo Operator Skin
• Calling Card (standard)
• 10,000 XP
• Unique Calling Card variant (complete before Directed Mode release)
• Animated Calling Card + 10,000 XP (Mastery Challenge)
• Additional XP + static Calling Cards (map challenges)
• Obsidian Sins reward: complete 25 rounds on Kowakujo
