When the Soshidō (祖師堂) was dismantled for repairs in 1987, evidence from the fabric and forty-five wooden tablets that were found suggested that the original form had been altered in the rebuilding of 1741. It was understood that originally the building resembled the Honden-Haiden of Kibitsu Jinja and, after an inscription was founded by the master carpenter of 1678 who came from that area, the hall was remodelled on that basis. A wooden shingle roof was installed and the old copper sold off for use by sculptors.[7]
