In November 2010, OYO Corporation, Pacific was established in Guam to provide geotechnical engineering and consulting services for the Guam Build-up which are comprised of projects for the U.S. Marines relocation from Okinawa to Guam.
In the last five years since the firm was established, OYO Corporation, Pacific has served numerous clienteles in geological investigations, laboratory tests, foundation design, geotechnical consulting and GIS services in Guam, Saipan, Chuuk and Diego Garcia. We are proud of our commitment to high quality service, especially in geophysical exploration utilizing nondestructive underground investigation without the need for intrusive digging or boring.
With various military project experiences in Guam, we recently began to expand our business to U.S military Installations in Japan. In February 2016, we opened a new office in Okinawa and have started to provide our services with the support of OYO group's high level technical engineering and support staff in Japan.
Please consider OYO Corporation, Pacific for your "Earth" related geotechnical and environmental engineering needs in the Far East and Pacific regions. We are committed to provide our services with a high emphasis on customer service, timeliness, providing a high level of cutting edge technological skill and with the enduring spirit of hospitality known in Japan as "O-Mo-Te-Na-Shi".
