It is a prefecture in the Kyushu region of Japan and is the smallest among the seven prefectures in Kyushu. The location of the prefectural government is Saga City. It faces Genkainada to the north, the Ariake Sea to the south, and is topographically divided into the Seburi mountains in the north, the Saga plains in the south, the hilly areas in the west, and the Dara mountains.

The remains of the ancient Japanese Yayoi period remain and are designated as Yoshinogari Historical Park. This is the first place in Japan where rice was cultivated. Saga Prefecture is a place with deep ties to Baekje in Korea, and the five-gyeong doctors of Baekje visited this place to deliver Baekje's cultural relics. Kakarashima, located in Karatsu, Saga Prefecture, is also known as the birthplace of King Muryeong of Baekje. The remains of the place where Toyotomi Hideyoshi built Nagoya Castle in Karatsu during the Japanese Invasion of Korea and Japanese troops left the site at that time.
