Dynamic Dialogue, Firmly Rooted in the Earth:
The Soil from which Our Dreams Grow.

Tokyo Soil Research Co., Ltd. prides itself on a long history of excellence as a construction
consultant focusing on ground surveys - the essential foundation of all fields of construction.
This success stems from the diligent devotion to meeting the constantly diversifying needs of ourcustomers, a stance that will continue to guide our endeavors from here on as well. Turning ourprofessional attention to the ground environment field, a critical theme of the 21st century, wesupply cutting edge technical services to support the creation of a new earth environment. Acting
as a loyal partner and a dependable advisor, Tokyo Soil Research is redoubling the drive to realize
the ever-growing dreams of our customers, and in doing so achieve our own towering goals.

Our Business Domains
The Prompt Supply of
Important and Equitable
Information
We gather basic information about
the ground, and furnish detailed
reports of our findings. Of particularimportance is the valuable data we
provide on the existence of active
faults, the history of liquefaction,land subsidence and other naturaltrends.

Research Expertise
Earning Absolute Trust
We plan and conduct optimum andeconomical ground surveys available.
These efforts encompass a broad rangeof phenomena, spanning urban, marine
and mountainous realms, including
critical environmental surveys. Our trackrecord especially shines in the research
we perform on structures that require
uncompromising resistance toearthquakes.

Meticulous Advice Basedon Ground Survey
Results
We consolidate genuinely
indispensable information about
the ground, indicate the detailed
soil characteristics at project sites,
propose design use groundconstants, conduct numericalanalysis, consult and design on abroad range of design andconstruction problems and furnish
other valuable services.

TechnologicalDevelopments

We perform stability analysis on
slopes and landslide areas, damgroundwater probes and otherwork necessary to recommend
optimum countermeasures. We
also propose methods formonitoring the likelihood of rockfalls, using wide-area rock fallmonitor systems on rock massslopes.

We are building a database of groundinformation, necessary for structuralmaintenance. We also perform soundness
evaluations, quake resistance diagnosis,
and seismic retrofitting design work forroads, bridges, buildings and otherstructures are also performed.

Our quality control system consistsof checks for boring, in-situ testingand other work, installation andobservation of equipment required
for effective computerization during
construction, consultation onproblems newly identified during
construction and other outstandingknow-how.

Global Network
Our business is spreading across national borders.
We will build a global network through technical collaboration and support withoverseas companies, actively cooperate with and support companies in the same way
in Japan, and aim for growth as a company.

Major overseas businesses
China, Taiwan, Korea, Philippines, Indonesia, Thailand, Iran, Iraq, Saudi Arabia, Yemen, Turkey, United States,Mexico, Peru, Chile, Ecuador, Sweden and Netherlands

Main technical collaboration
Upon establishment of the Peruvian earthquake disaster prevention center in Japan, we implemented technology
transfer, such as introduction of testing machines, survey, testing and analysis through JICA.
We regularly provide technical training to engineers visiting Japan from abroad.
In the survey of earthquake disasters, they will come to the scene as members of academic societies, universities,associations, etc., and report the results at academic conferences etc in Japan and abroad.
I participated in the preservation investigation committee of Machu Picchu ruins of Peru and cooperated withpreservation plan.
We are collaborating with IFCO of the Netherlands to develop measurement technology. In addition, we willconduct measurement work overseas jointly.
