Originally they were located only at Buddhist temples, where they lined the paths and approaches to the temple, but in the Heian period they began to be used at Shinto shrines as well.

The piece touching the ground represents chi, the earth; the next section represents sui, or water; ka or fire, is represented by the section encasing the lantern's light or flame, while fū (air) and kū (void or spirit) are represented by the last two sections, top-most and pointing towards the sky.
