This statue is "眼入", meaning that it has glass eyes painted with pupils inserted. The insertion of transparent eyes into Buddhist statues is a uniquely Japanese technique. One remarkable point of this technique is that when you look at this statue, your eyes will still match the eyes of the Buddha from any angle. Many people believe that this helps you appreciate the connection you have with the Buddha.
This Buddha statue's aura in the back has a unique, streamline design, which was inspired by the kurin (九輪), the nine vertically stacked rings on a Buddhist pagoda finial.
