Sendai

Although the Sendai area was inhabited as early as 20,000 years ago, the history of Sendai as a city begins from 1600, when the daimyō Date Masamune relocated. Masamune was not happy with his previous stronghold, Iwadeyama, which was located in the northern portion of his territories and was difficult to access from Edo (modern-day Tokyo). Sendai was an ideal location, being in the centre of Masamune's newly defined territories, upon the major road from Edo. Tokugawa Ieyasu gave Masamune permission to build a new castle in Aobayama after the Battle of Sekigahara. The previous ruler of the Sendai area had used a castle located on Aobayama. At this time Sendai was written as 千代 ("a thousand generations" or "eternity"). Masamune changed the kanji to "仙臺", which later became "仙台" (literally: "hermit/wizard" plus "platform/plateau" or figuratively, "hermit on a platform/high ground"). …

Sendai is the center of the Tōhoku region's economy, and is the base of the region's logistics and transportation. The GDP in Greater Sendai, Sendai Metropolitan Employment Area (1.6 million people), is US$61.7 billion in 2010. Sendai city by itself has a nominal GDP of approximately US$50 billion as of 2015. The city's economy heavily relies upon retail and services – the two industries provide approximately two thirds of the employment and close to half of the establishments.
