Wishing to be a detective who keeps running for smiles around the world! Teikoku Koshinsho, a comprehensive detective agency founded in 1950, built on tradition and trust.

We endorse April Dream, a project that aims to make April 1st a day for companies to announce their dreams. This press release is a dream of "Teikoku Koshinsho Co., Ltd."

Teikoku Koshinsho Co., Ltd. (Headquarters: Shibuya-ku, Tokyo; Representative Director and President: 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 Koshinsho Co., Ltd. has faced the "concerns" of numerous clients. 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 problems.

● A Detective Who Keeps Running for Smiles Around the World Our vision is not merely to remain an investigation company. Through the means of investigation, we aim to alleviate the anxieties of as many people as possible and help them regain their heartfelt smiles. To achieve this, we strive to be a runner who never stops, delivering peace of mind worldwide.

・Our Mission to Pursue "Smiles" Beyond Investigation Many people who require a detective are in deep distress and conflict. We want to help lighten that burden, even if just a little. Our true wish is not merely to complete an investigation, but for the results to bring "smiles" back to our clients' daily lives.

● "Watchful Eye Investigation" Gently Supporting Precious Family Members In response to the changing needs of society, we have launched a new investigation plan called "Watchful Eye Investigation." This plan is a service designed to discreetly confirm the safety and living situation of important family members, such as those living separately, under the concept of "gently watching over them."

・Reliable Peace of Mind Without Excessive Interference If family members try to resolve issues themselves, they might become overly involved due to worry, potentially straining 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 this new approach to investigation, which aligns with modern family structures, allowing people to feel connected even when apart.
