Beginning the quest
Head to the Shrine. Speak with Fuku, she will give you a fire amulet and a flint. Before you start the mission, you should visit the ship that is guarded by a few warriors. Collect all treasures and head towards the buildings. Walk carefully on beams because you can fall into water which results in instant death.
An archer will attack you when you reach the end of the first bridge. Any ranged weapon, that allows you to eliminate him quickly, will be useful here. When you cross the bridge, you should head left. Kodama is hiding behind the chests . Right next to it you can find a long corridor . From afar, you can notice a warrior investigating corpse but don't allow yourself to be fooled, he is only a decoy. When you try to approach him from behind, you will be immediately attacked by an enemy that jumps out from the left. Defeat them but don't let your guard down because there is another warrior hidden behind the altar.
The first lantern
On the right from the end of the pier you can find a lantern  which is presented in the picture. Lit it and prepare for a fight with a miniature version of the boss of this area. When the battle is over you must follow the only available path. A chest can be found in the building in front of you  but it is defended by a Yoki. Before you reach it, you can be attacked by a samurai on the right . Try to leave the narrow bridge as fast as you can.
After defeating the Yoki and collecting the treasure you can head towards the bridge on which you were attacked by the samurai. A warrior hides behind the wooden chests. Also, next to him, you can find the second Kodama of this location. When you are looking from the perspective from the picture above you can find an archer on the right. Eliminate him. Keep following the path if you want to continue the mission. You will be instantly attacked by a warrior that was lying on the pier.
You can notice a Shrine on the right but you can't access it yet. Head towards the chests presented in the picture. There is another warrior waiting for you behind the corner on the left.
You are now in the place presented in the picture above. There are two warriors on the right. Use the part of the pier, presented in the picture, to reach another part of the location. Use the passage that will take you on one the rooftops. Now, you have to face two snails. The archer behind the corner on the left makes this fight more difficult. Lure the snails out on the marked part of the pier. Remember that these enemies are very vulnerable to fire.
In front of you, behind the platform presented in the picture, you can find another Kodama.
The second lantern
In order to proceed further you must follow the path that leads right . In the place, where the skeleton stood, you now have to fight with a snail . Right next to that place you can find a gate , that leads to the Shrine that you saw earlier. You can't open it from this side. Besides that, here, you can also find an illusory wall . If you destroy it, you will be able to quickly reach another lantern . There are doors on both sides of the altar with the lantern. Those on the right can only be opened from the other side but behind those on the left you can find two skeletons and a chest with a treasure.
What is more, you can also find another Kodama behind the altar.
The second Shrine
Before you move to another part of the location you should get on a rooftop by using the previously mentioned passage. When you get there, you should go left and kill a skeleton that hides there. You finally reach a hole in the roof. If you go left, you will be above a chamber, the one that you saw a Yoki jumping into (the beginning of the location). Defeat the enemy and use the ladder to reach the Kodama presented in the picture.
If you go right then you will have to face a skeleton that patrols this part of the rooftop. When you defeat it, you must reach the end of the path. You can now see a Shrine below you.
Jump down, use the Shrine and follow the only available path that leads to the door. Open them and you will reach the starting point. The path in front of you leads to another part of this location, a burning lantern is on the left and a path that leads straight to the boss arena is on the right.
The third Shrine
Go through the door that leads to another part of the location.
The path ahead of you leads left but if you reach the edge of the wall on the right and go behind it, you will be able to find a Kodama hiding on a pier. Send the creature to a Shrine and head to the tipped ship. On the right, you will find a snail. Go straight ahead when you leave the shipwreck. Defeat a skeleton and you will reach a for.
Turn left and reach the end of the pier. The treasure, that you can see there, is guarded by a snail. When you defeat it, you must go back and then straight ahead. At the end of the path you can find a building with a Shrine but it is guarded by a Yoki hidden in a mist. If you want to reach that room, you must also defeat two skeletons. After that you can use the Shrine and walk around the building. You reach a ladder that can take you on its rooftop.
The third lantern
When you were near the Shrine, you could notice a Yoki that patrolled the area next to you but it was separated from you by deep water. When you get on the rooftop, you must head left and, soon, you will reach a ladder that can take you to that area. Watch out while you are going down the ladder because one additional move and you are in the water.
When you are facing the Yoki, you must only watch out for the holes in the pier. Besides that, you should have no problems with defeating it. After defeating the enemy, you can light up the last lantern in the area.
You must now return on the rooftop so go back to the ladder, the one that you used to get here. Reach the rooftop and go left.
Kodamas and Hot Springs
There are a few holes on the other side of the rooftop and behind them, there is another skeleton. You can notice a barge that crashed into the building, you can get inside it from the rooftop. A giant skeleton roams this area.
If you plan on fighting with this enemy then you must know that there is a small skeleton on the barge that will quickly join the fight. When you are done, you can go down a ladder and reach the lower level of the ship. There, you can find a Kodama. The second Kodama is below the footbridge that leads from the barge on the rooftop.
You can explore the area that was guarded by the giant skeleton but your overall goal is to go through the rooftop, left from the footbridge presented in the picture. This allows you to enter the tipped shipwreck, the one through which you passed before. On the right, you can find one skeleton with a bow. Kill the enemy and reach the end of the barge on the right. You can notice a snail below you. Jump down on it and hit the enemy while you are in the air.
Thanks to that, you reached an area that can't be entered via regular paths. A Kodama is in the same place in which you have fought with a snail. The path on the right leads to Hot Springs but on your way, there you can be attacked by two Yoki. After that you can use the springs.
In the same place you can find the last Kodama of this location. When you are heading towards the Hot Springs you simply have to go far to the left.
If you want to leave this area, you can use the door that will lead you to the house with the second lantern. By using the passage, you can easily access the second Shrine that is closest to the boss. You now have to fight with Umibozu. All tips for that fight can be found in the dedicated chapter.
