Miyagi prefecture (宮城県 Miyagi-ken) is in the northeastern Tohoku region of the main Japanese island Honshu.
WARNING: On 11th March 2011 the prefecture was hit by an earthquake with a 8.9 magnitude followed by a tsunami and several aftershocks. The Shinkansen connecting the capital, Sendai, with Tokyo resumed service on 25 April. While areas along the coast are still heavily damaged, the rest of the prefecture is operating as usual.
Miyagi prefecture has nothing to do with Mr. Miyagi from The Karate Kid.
