There are four Sign Stones in each area. If you find them all, they will decipher the Temple Sign in each area.

If you want to discover them for yourself, I recommend you use a controller. It will vibrate when you are near by.

Otherwise, here are screenshots and descriptions of where all the Sign Stones are.

By the hunting village, near a campsite. Can be seen from the pillar.

At the base of the waterfall, right behind the Temple Sign.

In the windmill terraces to the right of the Gate.

On the shoreline, in the Japanese village to the left of the Gate.

All of the sign stones are in the first area, before the sky bridge.

In the trees under the floating island village.

On the side of a mountain wall.

In a mountain range in the middle of the map, between the two ground villages.

In another mountain range in the middle of the map, near the floating island.

Turn right immediately after the first gate

The other three are all covered in snow, next to gazebo bonfires:

Along the path in the first outside area, next to the fourth gazebo bonfire.

In the second village (that also holds the temple), following the right wall.

After the ice gate, take the right path, and it's straight ahead.

If the sun is East:

On the west side (closest to starting location) of the base of the tall central mountain. (The temple is on the other side of this mountain.)

Near the right/south wall, near the path, between the first village and the beach village, below one of the last peaks.

Bottom of left/north side of drawbridge

Near the left/north wall, near the hill that divides the path near the canal village.

Summer: Be not afraid of growing slowly. Be afraid only of standing still.

Autumn: Climb the mountain to see the world, not so that the world can see you.

Winter: Be humble, for you are of the earth. Be noble, for you are of the stars.

Spring: Joy is the passage from lesser to greater perfection. Share it wherever you can.
