Our company endorses April Dream, which aims to make April 1st a day to share dreams. This press release is the dream of "Teikoku Koshinjo Co., Ltd."
Teikoku Koshinjo Co., Ltd. (Headquarters: Shibuya-ku, Tokyo; President & CEO: Takuji Taniguchi) was founded in March 1950 (Showa 25) and celebrated its 76th anniversary in March 2026.
We sincerely thank everyone for their long-standing patronage.
Since its establishment in 1950, Teikoku Koshinjo Co., Ltd. has faced numerous clients' "worries." We are proud that the investigation techniques and know-how cultivated over many years cannot be acquired overnight. This tradition is the driving force that leads to the resolution of worries.
● Detectives who keep running for smiles around the world
Our vision is not just to remain an investigation company. It is to remove anxiety from as many people as possible and help them regain their heartfelt smiles through the means of investigation. To achieve this, we aim to become a runner who never stops, delivering peace of mind to the world.
・Our mission to pursue "smiles" beyond investigation
Many people who need a detective are in deep trouble or conflict. We want to help lighten that burden, even a little. Our true wish is not just to complete an investigation, but for our clients to regain their "smiles" in their daily lives as a result.
● 'Watchful Eye Investigation' that gently supports loved ones
To meet the changing needs of society, we have launched a new investigation plan called "Watchful Eye Investigation." This investigation plan is based on the concept of "gently watching over" loved ones, such as family members living apart, and discreetly checking their safety and living conditions.
・Reliable peace of mind without excessive interference
If families try to resolve issues themselves, they might interfere too much out of worry, which could complicate relationships. However, we believe that detectives, skilled in observing human behavior, can provide reliable peace of mind by carefully noticing 'changes that must not be overlooked.'
We will continue to support more smiles with a new form of investigation that is close to the modern family structure, allowing them to feel connected even when apart. Learn more here ≫ https://www.teikokuweb.co.jp/investigation/mimamori/
