Aomori Prefecture shares border with Akita Prefecture
Aomori Prefecture (青森県, Aomori-ken) [a̠o̞mo̞ɾʲikẽ̞ɴ] is a prefecture of Japan in the Tōhoku region. The prefecture's capital, largest city, and namesake is the city of Aomori. Aomori is the northernmost prefecture on Japan's main island, Honshu, and is bordered by the Pacific Ocean to the east, Iwate Prefecture to the southeast, Akita Prefecture to the southwest, the Sea of Japan to the west, and Hokkaido across the Tsugaru Strait to the north. Aomori Prefecture is the 8th-largest prefecture, with an area of 9,645.64 km2 (3,724.20 sq mi), and the 31st-most populous prefecture, with more than 1.2 million people. Approximately 45 percent of Aomori Prefecture's residents live in its two core cities, Aomori and Hachinohe, which lie on coastal plains. The majority of the prefecture is covered in forested mountain ranges, with population centers occupying valleys and plains. Aomori is the third-most populous prefecture in the Tōhoku region, after Miyagi Prefecture and Fukushima Prefecture. Mount Iwaki, an active stratovolcano, is the prefecture's highest point, at almost 1,624.7 m (5,330 ft).
Humans have inhabited the prefecture for at least 15,000 years, and the oldest evidence of pottery in Japan was discovered at the Jōmon period Odai Yamamoto I site. After centuries of rule by the Nanbu and Tsugaru clans, the prefecture was formed out of the northern part of Mutsu Province during the Meiji Restoration. Though the prefecture remains dominated by primary sector industries, it also serves as a transportation hub due to its location at the northern end of Honshu.Geography
Aomori Prefecture is the northernmost prefecture in the Tōhoku region, lying on the northern end of the island of Honshu. It faces Hokkaido from across the Tsugaru Strait and it borders Akita and Iwate in the south. The prefecture is flanked by the Pacific Ocean to the east and the Sea of Japan to the west with the Tsugaru Strait linking those bodies of water to the north of the prefecture. The islets of Kyūroku-jima in the Sea of Japan are the prefecture's westernmost point. Oma, at the northwestern tip of the axe-shaped Shimokita Peninsula, is the northernmost point of Honshu. The Shimokita and Tsugaru Peninsulas enclose Mutsu Bay. Between those peninsulas lies the smaller Natsudomari Peninsula, the northern end of the Ōu Mountains. The three peninsulas are prominently visible in the prefecture's symbol, a stylized map.Lake Ogawara, a brackish lake at the base of the Shimokita Peninsula, is the eleventh largest lake in Japan, the largest brackish lake in the Tōhoku area, and the prefecture's largest lake. Lake Towada, a lake that sits in a volcanic caldera, straddles Aomori's boundary with Akita. The lake is a primary feature of Towada-Hachimantai National Park and is the largest caldera lake in Honshu. Also within the park, the Oirase River flows east towards the Pacific Ocean from Lake Towada. Another feature of the park, the Hakkōda Mountains, an expansive volcanic group, rises in the lands to the south of the city of Aomori and north of Lake Towada.Shirakami-Sanchi, a UNESCO World Heritage Site, is located in the Shirakami Mountains in the western part of the prefecture. The site contains the largest surviving virgin beech forest in East Asia which is home to over 87 species of birds. Mount Iwaki, a stratovolcano and the prefecture's highest point lies to northeast of the Shirakami Mountains. The lands to the east and northeast of Mount Iwaki are an expansive floodplain that is drained by the Iwaki River. Hirosaki, the former capital of the Tsugaru clan, sits on the banks of the river.As of 31 March 2019, 12% of the total land area of the prefecture was designated as Natural Parks, namely the Towada-Hachimantai and Sanriku Fukkō National Parks; Shimokita Hantō and Tsugaru Quasi-National Parks; and Asamushi-Natsudomari, Ashino Chishōgun, Iwaki Kōgen, Kuroishi Onsenkyō, Nakuidake, Ōwani Ikarigaseki Onsenkyō, and Tsugaru Shirakami Prefectural Natural Parks; and Mount Bonju Prefectural Forest.
