The Inner Sanctuary Scripture Repository in Koya-cho is a historic building built by Ishida Mitsunari for his mother. Its beautiful appearance and historical value are a must-see. The Korean version of the Tripitaka and the statue of Manjusri Bodhisattva housed here convey respect for Mitsunari's wisdom. This is the perfect spot for travelers who wish to deepen their knowledge and pray for academic improvement.
