You've probably seen the trailers by now. Naoe leaping across tiled roofs, Yasuke crushing samurai armor with a kanabo, and the lush, rain-slicked fields of Sengoku-era Japan. It looks incredible. But among all the flashy combat and the seasonal cycles Ubisoft is touting, there’s one specific location that has history nerds and hardcore fans buzzing: Nochiseyama Castle.
It’s not just another fortress.
When Nochiseyama Castle in AC Shadows was first spotted in promotional materials and gameplay deep-dives, it signaled something specific about the game’s commitment to regional history. This isn't just a generic "Japanese castle" template dropped into a map. Nochiseyama was the seat of power for the Wakasa Takeda clan. It sits in what is now Obama City, Fukui Prefecture. If you’re looking for the typical towering stone "tenshu" (keep) seen at Himeji or Osaka, you’re looking at the wrong century. Nochiseyama represents a transition. It’s a mountain castle—a yamajiro.
The Real History Behind Nochiseyama Castle
History is messy.
Construction started around 1522 under Takeda Motomitsu. Back then, castles weren't about looking pretty for tourists. They were defensive necessities built on steep ridges to make life a living nightmare for anyone trying to climb up with a spear. The Nochiseyama Castle AC Shadows experience reflects this rugged, vertical reality. You aren't just walking through a front gate; you're navigating earthen ramparts, dry moats called karahori, and dense foliage that actually served as a secondary defense.
The Takeda clan in Wakasa wasn't the same as the famous Takeda Shingen of Kai, though they shared lineage. They were stuck in a brutal tug-of-war between rising powers like the Asakura and the Oda. By the time our protagonists, Naoe and Yasuke, enter the fray in the late 1570s and early 1580s, Nochiseyama is a place of tension. It represents an older way of war.
- It was built on Mount Nochi.
- The site offered a strategic view of the Sea of Japan.
- It was eventually abandoned in favor of Obama Castle near the coast.
Ubisoft’s researchers clearly spent time looking at the topographical maps of Fukui. The way the game renders the terraced layers—the kuruwa—is surprisingly accurate to the archaeological remains found at the site today. You can still visit the ruins, though it's mostly stone foundations and earthworks now.
Stealth and Vertigo: Gameplay at Nochiseyama
Playing through Nochiseyama Castle in AC Shadows feels different depending on who you control. Honestly, it’s kind of a playground for Naoe. Because it's a mountain castle, the verticality is built-in. You’ve got these massive elevation shifts that allow for the classic "leap of faith" moments, but also more practical shinobi tactics.

Shadows are your best friend here.
The game uses a dynamic lighting system where you can actually douse torches or wait for clouds to cover the moon. In a yamajiro like Nochiseyama, this is lethal. You can crawl through the undergrowth on the steep slopes, bypass the main gate entirely, and infiltrate the lord’s residence at the summit. It’s satisfying. It feels earned.
Yasuke's approach to Nochiseyama Castle in AC Shadows is the total opposite. He’s a tank. While Naoe is busy sticking to the rafters, Yasuke is the one kicking down the heavy wooden doors of the mon (gates). The environmental destruction is key here. Those wooden fences and thin shoji screens don't stand a chance against a man of his stature. It creates this duality where the castle feels like two different maps depending on your playstyle.
Why the Location Choice is Actually Genius
Most games go for the obvious hits. Kyoto? Sure. Azuchi? Obviously. But choosing a site in Wakasa Province shows a deeper level of research. It moves the player away from the over-saturated central plains and into the rugged coastlines.
The Takeda clan’s decline is a perfect backdrop for an Assassin’s Creed story. They were caught in the middle of Nobunaga’s unification campaign. In the game, this gives the writers room to play with the Templar/Assassin conflict without tripping over the massive, well-documented battles every five minutes. It’s the "in-between" history where the best AC stories usually live.
Wait, did you know that Nochiseyama was one of the first places to really lean into the "wing-shaped" fortification style?
The builders utilized the natural ridges of the mountain, creating "wings" of defense that branched out from the central core. In the game, this means the layout isn't a simple circle. It’s a jagged, star-like sprawl. If you get spotted in one wing, you can potentially lose your pursuers by jumping a ravine into another section. It makes the AI pathfinding work for its money.

Dealing With the Accuracy Debates
Let's be real for a second. There’s been a lot of noise online about historical accuracy in this game. Some people get worked up about the architecture or the presence of certain characters.
But when it comes to the geography of Nochiseyama Castle in AC Shadows, the developers have stayed remarkably close to the physical reality of the 16th century. They’ve avoided the common mistake of putting 17th-century stone "tenshu" keeps on every hill. They understood that in 1579, many of these places were still largely wooden structures with thatched or shingled roofs.
The detail in the "Lord's Residence" area at the top of the mountain is particularly impressive. You see the transition from purely functional barracks to the more aesthetic shinden-zukuri influenced architecture that the Takeda lords favored to show off their cultural refinement. They wanted to prove they weren't just mountain warlords; they were men of the arts.
Exploring the Surroundings: Beyond the Walls
The area surrounding Nochiseyama Castle in AC Shadows is just as vital as the fort itself. The town of Obama (yes, that’s the real name) was a hub for trade. You’ll find merchants bringing goods from the northern provinces and even hints of "Nanban" (Western) influence starting to trickle in.
- The nearby temples provide sanctuary and high vantage points.
- The forest trails are perfect for ambushing Oda supply lines.
- The weather system—rain, fog, snow—completely changes how you approach the climb.
I’ve found that the best way to experience this specific location is during a thunderstorm. The mud affects your movement. It makes the slopes slippery. But the sound of the thunder masks your footsteps, making Naoe almost invisible. It’s atmospheric as hell.
Tips for Navigating Nochiseyama in AC Shadows
If you're planning on tackling this fortress, don't just charge the front gate. That’s a death sentence, even for Yasuke.
First, use your scout bird (or the equivalent reconnaissance tool) to map out the kuruwa. Look for the gaps in the palisades. There is almost always a drainage path or a servant’s entrance tucked away on the western slope.

Second, pay attention to the bells. Most Japanese castles of this era had a sophisticated alarm system. If a guard reaches the bell, the entire mountain will swarm you. In Nochiseyama, the bells are positioned at the "neck" of each ridge. Cut them off first.
Finally, use the grapple hook. AC Shadows brings back the grapple in a big way, and the rugged cliffs of Nochiseyama are exactly what it was designed for. You can skip three layers of defense just by finding a sturdy pine tree hanging over a precipice.
Final Thoughts on the Nochiseyama Experience
Nochiseyama isn't just a level. It’s a window into a specific, brutal moment in Japanese history. It’s where the old world of decentralized clans met the incoming tide of Nobunaga’s "Tenka Fubu" (unification under one sword).
Whether you’re a history buff or just someone who wants to do cool ninja stuff, the inclusion of Nochiseyama Castle in AC Shadows is a win. It shows a level of regional specificity that previous games sometimes lacked. It respects the terrain. It respects the era.
To get the most out of your time at Nochiseyama, follow these steps:
- Prioritize the "Eye of the Eagle" viewpoints early to clear the fog of war across the Wakasa coastline; it makes the mountain trails much easier to read.
- Invest in Naoe’s "Light Foot" skills before attempting the upper wards, as the wooden flooring in the Takeda residence is designed to creak and alert guards.
- Switch to Yasuke for the "Inner Sanctum" boss fights—the tight corridors of the mountain keep favor his high-impact, close-quarters combat style over Naoe’s wider arcs.
- Look for the hidden scrolls tucked away in the library wing; they provide the actual historical context of the Takeda clan's fall, which adds a lot of weight to the narrative.
The game doesn't hold your hand. The mountain is steep, the guards are alert, and the history is heavy. But that’s exactly why it works.
