Azuchi Castle is going to be one of the most difficult castles to clear in all ofAssassin’s Creed Shadows. It’s not just that it’s ahigh-level castle, and it is, but it also cannot be completed until you’ve progressed far enough in Yasuke’s story.
Azuchi Castle is going to be difficult for a couple of different reasons. One is that it’s a level 40 castle, meaning you’re going to need to be nearing that level to have a chance. Second is that the samurai that you’ll need to fight to clear this castle are in very claustrophobic conditions, making a fight against multiple enemies almost inevitable.

How To Find Azuchi Castle
Azuchi Castle isin the Omi region, which in itself is not a particularly high-level region. Azuchi Castle ison the eastern coast of Lake Biwa, and locatedacross the lake from Sakamoto.
Azuchi Castle itself has a large area, and much of it is not relevant to clearing the castle itself. Still, there are a lot of buildings to the south of it, as the land and structure climb upward.

How To Enter Azuchi Castle
There are quite a few ways to enter Azuchi Castle, which makes sense, considering its size.
It’s worth mentioning that there are large portions of the area where you’re allowed to be and won’t be attacked on sight. For the most part, the only areas where you’ll be immediately attacked are the main building and the Eastern Barracks. Unsurprisingly, those two places are where we’ll need to go.

There arefour different samuraiin Azuchi Castle, but they’regrouped in pairs.
First And Second Samurai
These two samurai arein the Eastern Barracks. This area is going to have a few regular enemies as well, two of which are sparring.
One of the samurai is going to bewatching the two people sparring. He’s not going to move unless something happens that he needs to investigate.
The other samurai is justsouth of this, on the outskirts of the barracks. This samurai isgoing to patrol back and forth, but still often inside of view of the other samurai.
The issue with these two samurai is that it’s going to be difficult to fight them individually. If you can manage to get a lethal assassination off, it’s going to help you immensely. The samurai watching the sparring match is a good choice for this since you can get behind him easily.
Third And Fourth Samurai
The other two samurai arein the main building of Azuchi Castle, which is the tallest structure. Specifically,one samurai is going to be on the second floor, andone samurai is going to be on the third floor.
This is going to be particularly complicated, andusing Yasukehere might make it quite a bit easier. This will be a claustrophobic fight, and enemies will jump into the fight late from other floors as they hear the commotion. Yasuke can hold his own in these situations better, whereNaoe isgoing to have some issues.
These areas are full of enemies, and pulling off an assassination is going to be extremely difficult. It’s not impossible, but expecting a fight is going to ensure that you’re at least ready for the worst-case scenario.
Where To Find The Legendary Chest In Azuchi Castle
The legendary chest in Azuchi Castle islocated on the third floor of the building, in the same room as the samurai on that floor. This chest is going tocontain the Ship Captain’s Mask for Yasuke, which is going to allow him to parry ranged attacks, sending them back at enemies.
Kano Painting
There is more to loot in this castle besides the legendary chest. There’s aKano Painting on the second floor, near the samurai on that floor. Since you’re likely to be fighting more or less everybody in the building, you’re probably going to be able to get that legendary chest and that painting at the same time, once everybody (but you) is dead.
Data Fragments
There is also a chest with data fragmentsin one of the upper floors of the castle. This floor isnot quite as heavily guardedas the floors below it, but the room in question will have a couple of enemies inside.
