Hidden chests that are revealed by equipping the Sacred Staff. They aren’t hard to find if you know they exist, but I thought I’d just compile the ones I found.
Spring Village

Behind Sakaki’s house, next to his garden

Autumn Village
On top of Yachiyo’s izakaya
Behind Cuilang’s house, behind the Mikoshi storage
Winter Village
Behind Fubuki’s shrine
Next to the waterwheel, behind Zaza’s smithy
Kagura Shrines
Spring Kagura Shrine, next to the right hind leg
Summer Kagura Shrine, straight across the stage

The one in the Spring Highlands
This one isn’t revealed by the Sacred Staff, and it shows up once you grow the trees around it using the Sacred Drum. It’s gray and it doesn’t show up in the map, like some of the other ones, so I thought I’d include it.
