Assassin’s Creed Shadows Makino Kurumazuka Kofun solution
Found to the south of Settsu, the Makino Kurumazuka Kofun in Assassin’s Creed Shadows reintroduces a return puzzle type from Assassin’s Creed games past: the sliding box puzzle.
But before you can even enter the tomb, there’s an interesting piece of game design to tackle. To solve the puzzle inside the mausoleum, you will need to pick up incendiary pots and carry them towards destructible rocks before detonating them.
To make sure you understand this, to enter Makino Kurumazuka Kofun you’re forced to take one of the red exploding pots from the crypt entrance and place it next to the rocks blocking the way down, then detonate it with a ninja tool, teppo shot or arrow from Yasuke’s bow.
Because of the weight of the boxes you need to move for the puzzle, you need to play as Yasuke to proceed.
Makino Kurumazuka Kofun solution
At the bottom, you find the way forward blocked by sliding boxes, but there’s a path forward to the right. Interact with the box in front of you, then slide it forward to proceed.
In the next chamber, slide the box in front of you out from blocking your path, then follow the stairs down and around. Take an exploding pot from your left and clear the blockage in front of you, then take another and destroy the rocks at the top of the stairs on the other side of the room.

Turn left at the fork to grab some extra items, then continue right. Swim across the pool in front of you, then climb the stairs on the other side. When you reach the next illuminated room, crash through the boxes on your right to reveal some more exploding pots. Throw one across the gap to rest at the bottom of the rocks blocking the path in front of you.
Go prone and crawl through the gap on your left. Now drop down and climb up the ledge in front of you to the other side of the room.

Climb the stairs here and you find yourself in a room with a couple of different boxes. Slide the horizontally shaped box to the front of the room, near the door you came in. Then slide the other box on the south wall to the other side of the wooden platform so the whole structure together makes a short bridge like the screenshot.

Now, go through the gap left by the second box in the south wall. Follow the stairs all the way around then slide the two boxes blocking your path out of the way. Now take an exploding pot from the floor and carry it across the bridge you made with the other boxes earlier.
Throw the pot across the gap and shoot it to make it explode and remove the final blockage. Follow the path around and claim your prize! To exit, slide the boxes on your right out of your way and run straight forward back out into the fresh air!
