We are proceeding with engineering investigation with the cooperation of laboratory of Associate Professor Oguchi of Saitama University to verify the soil quality etc. of the cave.

  • Based on the results of the data review, we suggested the necessity of renovation to the sealed gate to Josenji Temple.

  • We entrusted a grant from the East Japan Railway Culture Foundation for the sealed gate renovation project.

We spend a lot of time studying the "layer breaks" and "shell fossils" that can be considered in the cave.  We are also observing the geology of the neighborhood.

We obtained samples at two locations in the cave with permission from Josenji Temple. We took the samples back to our laboratory to conduct various laboratory tests.

洞内温湿度モニタリング調査

We have installed sensors called "data loggers" in the caves to monitor the weathering conditions inside the caves. Those sensors monitor the temperature and humidity inside and outside the caves once an hour.
