In different vignettes through the garden, boulders have been placed in vertical formations. The vertical boulders represent mountains as Japan is a mountainous country full of peaks and valleys. In Japanese culture, these rocks are considered heavenly.
Horizontal rocks are considered earthly and give shape to the garden. Horizontal rocks often represent islands since Japan is an island country.
These rocks are considered humanizing since they are in a neutral position.
650 tons of rocks were harvested from the Wisconsin Minnesota border, hand-picked, and hand-placed in the Kay McFarland Japanese Garden.
