The Location of Okayama Prefecture

Okayama Prefecture is located in the western part of Japan, in the central region of the Sanyo-do, and is an important transportation hub for the Chugoku and Shikoku areas, with the Seto Inland Sea to the south. The northern mountainous region is home to beautiful mountains and three famous hot spring areas, known as Mimasaka Santu.
Three major rivers, the Yoshii River, Takahashi River, and Asahi River, flow through the prefecture, contributing to its rich natural environment. The climate is known for being sunny, often referred to as the "Land of Sunshine," with a warm climate that supports abundant fruit production. The Seto Inland Sea also provides a variety of seafood.
In addition to its agricultural richness, Okayama has a high percentage of industrial production, with the Mizushima Industrial Zone being home to a wide range of major corporations in various fields.

Like other prefectures, Okayama is facing challenges related to a declining birthrate and an aging population, leading to anticipated labor shortages. The number of foreign workers in Okayama is approximately 20,000, with most coming from Vietnam, China, and the Philippines. About 40% of these workers are employed in manufacturing, while others work in wholesale and retail, construction, and various other industries.
In terms of residency status, nearly 40% are technical interns and those with visas based on familial or personal ties, making these the largest groups. Around 20% are in specialized or technical fields, while another 20% are engaged in activities outside their designated visa status. These foreign workers play an essential role in supporting Okayama’s labor market across a variety of sectors.
