Knowledge of Ehime and the Realities of the Private Investigation Market

Population of Ehime

According to the latest data, Ehime Prefecture has a population of approximately 1.33 million people. While it is the third most populous prefecture in Shikoku, the population has shown a steady decline in recent years due to aging and migration trends. For private investigations, this demographic profile means that communities tend to be closely connected, and movements can be easily noticed. Conducting discreet and professional investigations requires not only technical expertise but also careful adaptation to these local dynamics to ensure confidentiality and effectiveness.

Geographical location of Ehime within Japan and characteristics of the region

Ehime is located in the northwestern part of Shikoku, bordered by Kagawa to the northeast and Kochi to the southeast, with access to the Pacific Ocean in the south and the Seto Inland Sea in the north. The prefecture has a long and intricate coastline dotted with small islands, as well as mountainous inland areas. Its mild climate and scenic landscapes, such as the Setouchi Inland Sea, make it a popular location for tourism and business activities. For investigations, this diverse geography requires specialized planning, as cases may take place in urban centers like Matsuyama, rural mountain areas, or remote island communities.

Unique culture and local rules of Ehime

Ehime is famous for its citrus fruits, particularly mikan, and its long-standing traditions in industries such as towel production from Imabari. Cultural assets include Matsuyama Castle, Dogo Onsen, and Shikoku’s pilgrimage routes, which are well known to both domestic and international visitors. The region values strong community bonds and cultural pride, making discretion essential when conducting investigations. Understanding the importance of these traditions and the role of local customs ensures that investigations are carried out respectfully and effectively in Ehime.

Number of licensed private investigation agencies in Ehime

The latest confirmation shows that four licensed private investigation agencies are officially registered and operate within Ehime Prefecture. Compared to Japan’s major metropolitan areas, this is a small number, emphasizing the limited options available locally. For overseas clients, access to a nationwide agency with strong networks and English-language support is crucial. Detective Agency Japan provides this capability, ensuring professional, discreet, and legally compliant investigations across Ehime, regardless of whether the case involves urban districts or more remote island locations.
