Attention is also being paid to the relationship with Shinraku-ji temple (新楽寺) that used to exist somewhere in the area (Moriya or Muraya [reading unknown] which may refer to Iyoto-mura village in the northeast) but does not exist anymore.
また、現存していないが、付近（杜屋、村屋？：東北方向の伊与戸村のことか？）に新楽寺（しんらくじ）という寺がかってあり、関係が注目される。
