It sits along the Bungo Channel, which acts as a water link between the Pacific Ocean and the Seto Inland Sea. The prefecture is positioned across from Ehime Prefecture on the island of Shikoku. To the north, it is bordered by the Suo Channel and Honshū Island. Its land neighbors include Fukuoka Prefecture to the northwest, Kumamoto Prefecture to the southwest, and Miyazaki Prefecture to the south. With a total area of 6,340.71 square kilometers, the region is a diverse mix of mountains, forests, and coasts.

The physical landscape is shaped by complex geological forces. A major tectonic line runs from Usuki City in Ōita to Yatsushiro City in Kumamoto. Other tectonic lines run east to west through the prefecture. These movements have created a varied terrain. The northern part features granite and metamorphic rocks. In contrast, the southern area contains limestone. This limestone serves as the foundation for the Tsukumi cement industry and forms several limestone caves. The Kirishima Range is a volcanic belt that runs vertically through the prefecture. This volcanic activity is responsible for the many hot spring sources found here.

Nature dominates much of the Ōita landscape. Approximately 70% of the prefecture is covered by forests. Massive mountain ranges rise above the land, including Mount Yufu, Mount Tsurumi, Mount Sobo, Mount Katamuki, and Mount Kujū. Mount Kujū is often called the "roof of Kyūshū."

These mountains feed many important water sources. Major rivers include the Yamakuni, Yakkan, Ōita, Ōno, and Banjō rivers. The coastline varies greatly depending on the location. The north features shoals, while Beppu Bay sits in the center. The southern coast is a jagged "rias coastline." In Saiki City, the Yakata Island area contains rare sea cliffs and sedimentary rock formations.

The history of the region stretches back many centuries. Around the 6th century, Kyūshū was divided into four regions: Tsukushi, Hi, Kumaso, and Toyo provinces. Toyo Province was later split into Bungo and Buzen provinces. After the Meiji Restoration, these two provinces were combined to form the modern Ōita Prefecture. An 8th-century report mentions Emperor Keikō visiting the area. He reportedly named it Okita-Kuni, meaning "Land of the Great Fields."

Today, modern interpretations suggest the name comes from "Okita," meaning "many fields," due to the complex terrain. During the Edo period, the town of Hita served as a government seat. Hita became famous for the Hita-kin money-lending industry, managed by merchants in the Mameda and Kuma districts.

Ōita is a major center for tourism and specialized industry. It is the most famous prefecture in Japan for its onsen, or hot springs. It has more onsen than any other prefecture in the country. The city of Beppu is a primary destination for travelers seeking these springs and traditional ryokan inns.

Beyond tourism, the prefecture is a leader in several agricultural products. It is Japan's top producer of kabosu limes, which are citrus fruits rich in vitamin C. It also leads the nation in the production of dried shiitake mushrooms. In the Taketa area, Ōita produces 80% of Japan's total saffron. The prefecture is also the top producer of madake bamboo and galingale.

The economy is supported by diverse natural resources and manufacturing. Ōita ranks first in Japan for limestone production. It also ranks first for hot-spring output and geothermal power. The prefecture is second only to the United States' Yellowstone National Park in geothermal output. Agriculture is a primary industrial driver, including dairy farming on the Kujū highlands. The fishing industry is also prosperous, utilizing the rich coastal waters. Many large international companies, such as Sony, Canon, and Toshiba, operate factories within the prefecture.

Modern Ōita is organized into 14 cities, 3 districts, 3 towns, and one village. The population was recorded at 1,081,646 as of February 1, 2025. The prefecture has undergone significant municipal changes. Between 2005 and 2006, many smaller municipalities merged. This resulted in Ōita having the fewest municipalities in Kyūshū. It also has the fewest towns and villages combined in all of Japan. The "One Village One Product" movement, led by former governor Morihiko Hiramatsu, helped boost the local economy. This movement has since gained international attention for helping local industries grow.
