Mausoleum buildings of Masumune family, 1600's Samurai Lord of the Date Clan. This mausoleum complex celebrates first lord of Sendai, Masamune Date. As a Samurai, Masumune allied with leaders in old Japan...and was highly revered in the Samurai Culture. He is a famous figure in Japan even today. The original structure was built in 1637 by Masamune's son Tadamune. It was a beautiful Momoyama-style building, built by the best architects of the day, and was designated a National Treasure in 1931. Unfortunately, it was destroyed by fire during World War II. The site was excavated and studied by an archaeological team, and the Zuihoden was rebuilt in 1979. Also on the site are the Kansenden and Zennoden, mausoleums of the second and third Sendai lords Tadamune and Tsunamune, as well as graves of the ninth and eleventh lords and some of their children. There is a museum where one can watch a 20-minute video of the archaeological dig, view some of the artifacts, and even figures of the three lords, based on the actual remains. The mausoleums are exact replicas using the original designs of each building.
