The Location of Saga Prefecture

Saga Prefecture is located in the northwestern part of Kyushu, facing the Genkai Sea to the north and the Ariake Sea to the south. To the north, the Sekibumi Mountain Range stretches across the area, while the Saga Plain spreads to the south, offering picturesque rural landscapes.
In addition to rice, Saga is the second-largest producer of onions in Japan, following Hokkaido. The prefecture also has a strong fishing industry, known for the nori (seaweed) farming and Yobuko squid. Additionally, Imari, Arita, and Karatsu pottery are world-famous, and the region is rich in historical traditions such as hot springs and festivals.
Saga is home to the nationally designated Yoshinogari Ruins, a historical site that provides insight into the ancient Jomon period. The climate is mild, with the mountainous areas receiving more rainfall compared to the plains.

Like other prefectures, Saga is facing challenges from a declining birthrate and an aging population, which is expected to lead to labor shortages. The number of foreign workers in Saga is approximately 5,000, with the majority coming from Vietnam, China, and Nepal. Over 50% of these workers are employed in manufacturing, while others work in transportation, postal services, hospitality, and food services.
In terms of residency status, nearly 50% are technical interns, making this the largest group. Around 30% are engaged in activities outside their designated visa status, while about 10% hold residency based on familial or personal ties. These foreign workers are playing a significant role in supporting Saga’s labor market across various sectors.
