Oita Prefecture is located in the northeastern part of the Kyushu region and is divided into four regions: northern, central, western, and southern. With an area of approximately 6,340 square kilometers, it is the 22nd largest prefecture in Japan. Due to its complex topography, the prefecture boasts the largest number of tunnels in Japan, with 494 tunnels. The northern part belongs to the Seto Inland Sea climate zone, but in winter, cloudy weather is common due to the monsoon from the Kitakyushu area and the Kanmon Straits. The central part of the country enjoys better weather than the northern and western parts during the winter monsoon season. The western part of the prefecture is inland, so thunderstorms are more frequent in summer. The southern part of the prefecture is the warmest and wettest area in the prefecture. Suppon (soft-shelled turtle) grown in Oita Prefecture is famous for its high quality due to the clean, clear water and mild climate. Other recommended products include Bungo beef, which is raised in Oita's blessed natural environment and has a glorious history and proven track record, and Kuramitsu, which is made using subsoil water from the Ono River, which has the highest water quality in Japan. Oita Prefecture is also famous for its hot springs, and you should not miss Beppu Jigoku Meguri, a tour of seven distinctive hot springs, including the Blood Pond Hell, Takegawara Onsen, and Hyotan Onsen, with its "waterfall bath" that offers excellent massage effects. The Usa Jingu Shrine, with its beautiful white walls and vermilion-lacquered pillars, is also worth a visit.
