50 Years of Experience and Achievement

Started manufacturing and selling geological survey components in 1973

Ten years later, we began selling W core tube for soft soil to medium-hard rock. We directly sell and deliver to sites in all prefectures of Kyushu, Yamaguchi Prefecture, and Shikoku, developing core tubes based on field experience that can sample from soft soil to soft rock to medium-hard rock to ultra-hard rock in contiguous fields. Now, we receive tremendous support and patronage throughout Japan and in some parts of overseas.

History of CorePack Tube® Sales

Over 38 years, numerous earthquakes have occurred, including the 1995 Great Hanshin Earthquake, the 2011 Great East Japan Earthquake, and earthquakes in Kumamoto, Hokkaido, etc. The geological survey business has expanded, and the demand for high-quality core sampling has naturally become more critical. Easy-to-use and convenient machinery and core tubes have become essential for field engineers, leading to increased demand. Our products have reached approximately 30,000 sets sold.
