Knowledge of Kagawa and the Realities of the Private Investigation Market

Population of Kagawa

According to the latest data, Kagawa Prefecture has a population of around 910,000 people. Official estimates confirm a steady decline compared to previous years, reflecting trends of aging and depopulation. As Japan’s smallest prefecture in terms of land area, communities are compact, and social connections tend to be close-knit. For private investigations, this demographic structure means that discretion and sensitivity are essential, as unfamiliar activity can quickly attract attention. Careful planning and knowledge of the social environment are vital for carrying out effective and confidential operations.

Geographical location of Kagawa within Japan and characteristics of the region

Kagawa is located in the northeastern part of Shikoku, bordered by Tokushima to the east and south, and Ehime to the west. To the north, it faces the Seto Inland Sea and connects to Okayama on Honshu via the Seto Ohashi Bridge. With an area of less than 1,900 km², it is Japan’s smallest prefecture, but its geography is diverse, including thousands of reservoirs, coastal plains, and island communities such as Naoshima and Shodoshima. The region has a mild climate with frequent sunshine and relatively few natural disasters. For investigations, these conditions provide a favorable environment but also require specialized local knowledge to navigate both urban centers and island areas.

Unique culture and local rules of Kagawa

Kagawa is widely known as “Udon Prefecture,” with Sanuki udon deeply embedded in local culture. There are said to be more udon shops than convenience stores, reflecting its strong cultural identity. Beyond cuisine, Kagawa is home to notable specialties such as olives from Shodoshima, artisanal Wasanbon sugar, and local dishes like bone-in chicken. The prefecture also hosts the Setouchi Triennale, an international art festival held on its islands, and landmarks like Ritsurin Garden and Kotohira Shrine attract visitors from around the world. These cultural features shape how people interact, making respect for local customs and community dynamics an essential part of conducting investigations in Kagawa.

Number of licensed private investigation agencies in Kagawa

The latest confirmation shows that there are four licensed private investigation agencies officially registered and operating in Kagawa Prefecture. This small number underlines the limited availability of specialized investigative resources in the region compared to larger urban areas. For overseas clients, this means that relying on a nationwide organization with established networks and English-language support is crucial. Our agency fills this gap by providing dependable investigative services in Kagawa, ensuring that clients abroad can access trustworthy and professional support in one of Japan’s most compact but culturally distinct regions.
