Several students from our laboratory visited the technical center of Earth Prime Co., Ltd. in Tokorozawa City, Saitama Prefecture, as part of a collaborative research project on chemical grouting. During the visit, the students were able to see testing equipment that our laboratory does not have, and especially the well-organized testing room attracted the interest of the students, including the international students. Through this visit, the students were able to gain a valuable opportunity to experience the cutting edge of soil testing and deepen their knowledge.
