OUR STRENGTH / LOCAL EXPERTISE
Why can TSK INTERNATIONAL's investigations
achieve both accuracy and cost-effectiveness?
Professional investigation skills × more than 10 years of local experience.
Knowing the local area is the first step toward reducing wasted investigation effort.
TSK INTERNATIONAL has Japanese advisors who have lived locally for more than 10 years in each of the Philippines, Thailand and Vietnam. We have them on our team.
This is an overwhelming strength thatother investigation agencies do not have,and it sets us apart.
In overseas investigations, unnecessary travel and detours can occur if one does not understand local conditions, the transportation environment, daily customs and how information is gathered. Advisors with thorough local knowledge guide investigators who have specialized investigation skills on what to verify first and which methods to prioritize.
As a result, we aim to create investigation plans that keep unnecessary steps and costs down while focusing on confirming the facts you need. Combining "investigation skills" with "thorough local knowledge" is our agency's greatest strength.

About the Cases Shown

CASE 01 Philippines / Person Search & Whereabouts Check
Suddenly unable to reach
a family member in the Philippines
Hypothetical Inquiry
I have been unable to contact a family member living in the Philippines for several weeks. I know the address where they used to live, but I don't know whether they still live there. I am worried that they may have had an accident or fallen ill, and I would like to confirm their current whereabouts and well-being.
Our Approach
We organize the available leads, such as name, photographs, the last confirmed address, contact history and social media. Taking local conditions and laws into account, we consider lawful methods that can be used to confirm whereabouts and well-being.

CASE 02 Thailand / Infidelity & Conduct Investigation
Concerned about a spouse's
behavior during business trips to Thailand
Hypothetical Inquiry
My spouse travels to Thailand frequently on business, but lately the explanations about the length of stay and accommodation have become vague. I worry that they may be in a close relationship with someone there. I want to decide how to proceed based on confirmable facts, not speculation.
Our Approach
We review the information already known, such as the business trip schedule and place of stay. Based on the purpose of the investigation and the target area, we consider whether activity checks that comply with local laws can be carried out, and we define the necessary scope of investigation.

CASE 03 Vietnam / Corporate Credit Investigation
Wanting to know whether a Vietnamese
business partner can truly be trusted
Hypothetical Inquiry

Wanting to verify the background and
living circumstances of a prospective international spouse

ANSWER
Yes. You can consult us about an overseas investigation from Japan. First, please tell us your current situation and the purpose of the investigation through the contact form or similar channels.
We will guide you step by step through confirming the necessary information, proposing investigation methods, providing a quote, and the contract procedures.
Q04 Can you investigate countries other than the Philippines?
ANSWER
At TSK INTERNATIONAL, while our main focus is the Philippines, we also accept inquiries about overseas investigations in countries such as Thailand and Vietnam.
Whether we can assist depends on the target country, investigation area, content, and local laws and conditions. Please first let us know the target country and what you would like to confirm.

It helps to start by organizing the country concerned, what you would like investigated, the information you currently have, and any points you particularly want to confirm. This makes the consultation easier to move forward.
