Artifact no. 2 - Noppera-Bo
The secret can be found shortly after obtaining the previous collectible, i.e. in the first part of the contaminated village. After reaching the first big bonfire, check inside the hut on the left from the above screenshot.
This is the final secret to be obtained in the first part of the contaminated village, before encountering the first monsters. To find it, head to the right of the first bonfire. You'll reach the location pictured in the screenshot with the second bonfire and the upgrade sitting next to it.
Artifact no. 3 - Otoroshi
You can get this collectible shortly after defeating the first enemy samurai. You'll reach a shrine, but instead of immediately heading right, check out the left roofed area pictured in the screenshot above.
This secret can be obtained immediately after finding the third artifact described above. Keep going to the left of the shrine. You'll reach the side location from the screenshot, where you'll find the upgrade.
Artifact no. 4 - Hitotsume-Kozo
This artifact is obtained shortly after getting rid of the group of monsters by sabotaging the dam mechanism on the river. After the sabotage, head to the building on the right. The collectible will be on the ground floor.
This secret can be found soon after obtaining the fourth artifact described above. Use the ladder in the same building to reach the attic. Eliminate the monster there and reach the section of the attic to the right, where you'll find the collectible.
Artifact no. 5 - Yurei; Stamina Upgrade
Both of these secrets are in the same hidden location. Soon after defeating one of the samurai, you'll reach the fork in screenshot no. 1 and you'll have to head right. You will reach the location from screenshot no. 2, where you have to knock over the tree and walk over it to the rock shelves with collectibles.
Artifact no. 6 - Uwan
You can find the secret shortly after defeating the third samurai encountered on the bridge. After you get off the bridge, take the left path first and you will reach the area with the collectible pictured in the screenshot above. Watch out for cocoons while trying to collect the artifact.
You'll find this upgrade soon after finding the 6th artifact described above. After reaching the location from screenshot no. 1, go down the left ladder first. You will reach the pier from screenshot no. 2 and you'll find the secret at its end.
Artifact no. 7 - Nuppeppo
Start searching for this artifact once you arrive in the section of the village from screenshot no. 1. From here, you'll need to take the less obvious path to the left. You'll reach the area with the cage from screenshot no. 2 and the artifact will be lying next to the cage.
This secret can be found once you've reached the area with footbridges resembling a small maze. You have to reach the footbridge at the bottom of the screen.
Bo-Shuriken Upgrade; Stamina Upgrade
You can obtain both secrets shortly after dealing with Morimitsu and a group of samurai. After you reach the village section from screenshot no. 1, check out the obscured side passage on the left. Both collectibles are next to the cage from screenshot no. 2.
Artifact no. 8 - Inugami
You can get the secret shortly after reaching the location of the shrine with a ladder next to it. Use the ladder to reach the marked collectible from the upper balconies.
You can get the upgrade right after obtaining the 8th artifact. Enter the building where you previously found the aforementioned collectible. Inside you will find the secret you are looking for.
The upgrade can be obtained after reaching the large tower. Use the ladder to get to the very top, i.e. to the place where you can start a fire. The collectible is on the right (the picture above).
Artifact no. 9 - Ushi-Oni
This artifact can be found after the escape from the tower sequence (the one involving the crumbling bridge). Once you've arrived in the area from screenshot no. 1, you'll need to climb to the ledge on the right. The game will load a separate side area here, where you can easily find the secret (screenshot no. 2).
Artifact no. 10 - Yamawaro
This collectible is in a very obvious location, near the path leading towards this chapter's boss fight. You'll reach the location pictured in the screenshot once you've descended down the steep slope.
