The Location of Kumamoto Prefecture

Kumamoto Prefecture is located in the center of Kyushu and faces the Ariake Sea. The prefecture is sometimes referred to as the "Land of Fire" due to the presence of Mount Aso, one of the largest active volcanic craters in the world, located in the eastern part of the region. Kumamoto is also known for its numerous hot springs, with many distinct and unique hot spring towns scattered throughout the area.
In the vicinity of Mount Aso and the Kyushu Mountains, livestock farming and forestry are common, while the western part of the prefecture features expansive plains along the Ariake Sea. This area is a rich agricultural zone, serving as both a major grain-producing area and a hub for commerce and industry.
Kumamoto is particularly renowned for its production of rush (igusa), which is used in tatami mats. Agriculture is a major industry, and the prefecture boasts the highest production of tomatoes and watermelon in Japan. Among the famous local dishes is karashi renkon (mustard-stuffed lotus root). Kumamoto is also known for its horse meat production, with basashi (raw horse meat) being a local delicacy.

Like other prefectures, Kumamoto is facing challenges from a declining birthrate and an aging population, leading to anticipated labor shortages. The number of foreign workers in the prefecture is slightly over 10,000, with most coming from Vietnam, China, and the Philippines. Around 30% are employed in manufacturing, while nearly 20% work in agriculture and forestry. Others are employed in wholesale and retail, construction, and various other industries.
In terms of residency status, nearly 60% are technical interns, making this the largest group. Those in specialized or technical fields account for just under 20%, while individuals with visas based on familial or personal ties make up around 10%. These foreign workers are playing an important role in supporting Kumamoto's labor force across a range of industries.
