About Goro KOYAMA

Goro KOYAMA

When I was a kid, I liked surprising people by doing or telling something rare.

My paternal grand father was a serviceman of Japanese Navy during WW2. So I am fascinated by a survival games, mercenaries, street fighters. I am always thinking I could be a good serviceman in a war time.

My maternal grand father was a president of an international trading company of textiles. So I have had a strong interest in diplomatic matters from my childhood.

When I was in university, I seriously practiced full contact martial arts powerhouse in the college league. But as I was not an elite athlete, I broke my elbow and both knees.

While attending university, I had a strong interest in field works of researching on the hidden side of life or society and international matters including migration. In that course, I experienced a variety of fishy or illegitimate part time works. And the lure of doing fieldwork was too exciting for me. So I dropped out of college to pursue my passion in life, to become a Private Investigator where your main goal is uncover the hidden side or life or society.

I took a job at a local PI firm in Tokyo in 1992 and apprenticed as an investigator for 10 years, then founded my own agency in 2002.

I have never lost my curiosity in foreign matters and hidden facts of life since my childhood, so I am addicted to learn English by preventing myself from watching or reading Japanese other than work and look up online articles about untold stories or tools to uncover hidden facts.

What I do for a living now will be fitting with all my traits from my youth.
