About the sacred tree

As a sacred tree, the branch of mulberry tree is used to make the bow used in a ritual called “Ufuyumi” for the effect of expelling evil spirits. As the mulberry tree is also related to the sun of god, the people in Okinawa say “Kwahgi nu shita (or shicha) dehbiru (I am under a mulberry tree so please don’t strike.)” when there is a thunderstorm.
