Assassin’s Creed Shadows: How to Get the Legendary Namazu Horse Mount

The hidden underwater cave on Okishima holds the only free Legendary mount in the game. Here’s the exact route to reach it.

The Namazu mount is the only freely obtainable Legendary mount in Assassin’s Creed Shadows, and it can be found in a hidden underwater cave beneath Okishima Island in the Omi region. The game never points you toward it, no quest directs you, and you might walk right past the entrance without realizing a rare mount is sitting at the bottom of Lake Biwa. This guide explains how to get the Legendary Namazu Horse Mount in AC Shadows, including its exact location.

Where to Find the Legendary Namazu Mount in Assassin’s Creed Shadows

Okishima Island is located in the middle of Lake Biwa in the Omi region. It’s easy to reach if you have unlocked the Okishima Kakurega or visited the lake during story missions. But even if you’re here for the first time, a fishing boat from the River Boy Hamlet shore will take you to Okishima.

The Legendary Namazu Mount can be collected from a chest in an underwater cavern on the western shoreline of the Okishima Island, west of the Okishima Kakurega. Ride along the shore to find a large bonfire beside a wrecked boat, usually with a few bandits milling around, so kill them first if you encounter.

Stand on the lakebank between the bonfire and the cherry blossom tree, dive into the water from there, and swim straight down. Once underwater, turn toward the island and follow the entrance through the stone wall. A narrow tunnel opens beneath the ledges, which is the hidden cave. There’s not much breathing room in water, so move through the tunnel fast until it widens into a cavern chamber. There’s an air pocket here where you should stop for a while to refill your stamina before diving again.

How to Equip the Namazu Mount

Open the Inventory and select the Mount slot next to the secondary weapon. Every mount you’ve unlocked, including Namazu, will appear in this menu. Choose the Namazu Mount to equip it. Since the creature’s body shape differs from normal horses, you can’t apply saddles or mount cosmetics on this horse—what you see is what you get.

What is the Namazu Mount

Namazu Mount in AC Shadows

The Namazu takes its inspiration from the giant catfish in Japanese legends—huge creatures you’d find in rivers, considered responsible for earthquakes and strange happenings beneath the water. You see the myth come through in the mount’s design: the scales, the long whiskers hanging from its face, and the muddy colors that resemble the water near Lake Biwa. Even the in-game description hints at its water-loving roots.

Looks aside, the Namazu is exactly like a regular horse with the same speed, turns, and everything. Don’t expect it to pull off any water moves—it won’t swim across deep lakes. If you try to push it too far, Yasuke or Naoe will end up taking a swim. It’s exclusive to cosmetics, but it’s one of the best mounts in Assassin’s Creed Shadows and the only Legendary mount you can earn for free without purchase.
