My ol' hometown (Sendai) for a year and a half in the mid-50s. Nice to catch a bit of history related to the city.

A bit more about Sendai from WikiLeaks ..

Sendai Domain was a Japanese domain of the Edo period. Most of its holdings were contiguous, covering all of present-day Miyagi Prefecture, small portions of southern Iwate Prefecture, and a portion of northeastern Fukushima Prefecture.

The domain's capital, and the ruling family's castle, were located in what became the modern city of Sendai. Ruled for the entirety of its history by the Date clan.

It constituted the largest domain in northern Japan, and one of the largest domains in the entire country, after the Satsuma Domain and Kaga Domain.

Sendai was the focal point of the Ouetsu Reppan Domei during the Boshin War. Unlike the nearby Aizu domain, Sendai survived the war largely intact, though with a severely reduced income. It was disbanded with the other domains in 1873.
