Finished !
Wishing a quick and complete recovery to the all victims of
the Noto Peninsula Earthquake in 2024.
At 16:10 on 1 January 2024, there was a magnitude 7.6 (preliminary) earthquake in the Noto region of Ishikawa Prefecture, Japan.
Many roads are reported to be sinking or collapsing. Rescue operations in the affected areas have been delayed because of these problems.
We wish our deepest sympathies to all people who are staying at home or in shelters in the cold winter days.
We also pray for you to rebuild the region with great strength.

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.
Geological field survey
地盤地質 現地確認
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.
Sampling
サンプリング
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.
Temperature and Humidity monitoring in Taya Cave
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.
