A gold-plated necklace designed to represent the movement of the brush when writing the "Bonji", which represents each of the three Yakushi Buddhas: Yakushi Nyorai, Nikko Bosatsu, and Gakko Bosatsu. The fine surface processing is beautiful, and although it has a delicate design, it emits a gorgeous shine. Yakushi Sanzon is Yakushi Nyorai, who is said to have the merit of healing all kinds of illnesses. Together with the Nikko Bodhisattva and Moonlight Bodhisattva that follow on both sides, it is said to be a Buddhist statue enshrining style called 'Yakushi Sanzon'. With Yakushi Nyorai at the center, Nikko Bodhisattva is the left side attendant, and Gekko Bosatsu is the right side attendant.
