Miyagi Prefecture

Miyagi Prefecture sits in the central part of Japan’s Tōhoku region, on the island of Honshu. Its neighbors are Iwate to the north, Akita to the northwest, Yamagata to the west, and Fukushima to the south. The prefecture faces the Pacific Ocean on its eastern side, and its western border runs along the Ōu Mountains, the longest mountain range in Japan. The capital, Sendai, is also the largest city in the entire Tōhoku region. Other major cities include Ishinomaki, Ōsaki, and Tome. As of August 1, 2023, the population stood at 2,265,724, spread across an area of 7,282 square kilometers. About 24 percent of that land falls within Natural Parks, including Sanriku Fukkō National Park, Kurikoma and Zaō Quasi-National Parks, and several prefectural parks. Near the town of Matsushima, the Matsushima Islands—a bay dotted with 260 small, pine-covered islands—are counted among the Three Views of Japan.

Historically, this area was part of the old province of Mutsu. The prefecture is especially prone to earthquakes, even by Japanese standards. Large quakes frequently occur off its coast, and inland tremors are common. The most devastating event in recent memory was the March 11, 2011, Tōhoku earthquake, a magnitude 9.0 event that generated a major tsunami. The tsunami, estimated to have reached about 10 meters high in Miyagi, caused severe damage. A month later, on April 7, a magnitude 7.4 earthquake struck off the coast, prompting another tsunami warning and the evacuation of workers from the troubled Fukushima Daiichi Nuclear Power Plant. Residents were told to move inland. In 2013, Crown Prince Naruhito and Crown Princess Masako visited the prefecture to see the recovery progress.

The geography features high mountains in the west and along the northeast coast, but a fairly large central plain surrounds Sendai. The Oshika Peninsula projects from the northern coastline. The prefecture’s economy relies on fishing and agriculture—producing rice and livestock—but manufacturing around Sendai dominates, especially in electronics, appliances, and food processing. As of March 2011, Miyagi accounted for 4.7 percent of Japan’s beef cattle, 23 percent of its oysters, and 15.9 percent of its sauries. In July 2011, the government banned shipments of beef cattle from the prefecture due to fears of radioactive contamination, though that ban was later lifted.

Demographically, the prefecture saw its fastest growth between 1940 and 1950, with continued growth into the 21st century. Like much of Japan, the overall population has since begun a slow decline, though Sendai itself has seen a moderate, steady increase over the past twenty years. The prefecture hosts numerous universities, including Tohoku University, Miyagi University, and several others. Transportation is served by JR East lines, including the Tōhoku Shinkansen, as well as the Sendai Municipal Subway, Abukuma Express, and the Sendai Airport Line. Major expressways include the Tōhoku, Yamagata, and Sanriku Expressways. Ports in Sendai and Ishinomaki handle ferries and cargo, and Sendai Airport provides air service. Sports teams based in the prefecture include the Tohoku Rakuten Golden Eagles (baseball), Vegalta Sendai (soccer), Sendai 89ERS (basketball), and Sendai Bellefille (volleyball). Sendai itself was the castle town of the daimyō Date Masamune, and the remains of Sendai Castle stand on a hill above the city.
