Kanrantei (観瀾亭) is the only building to survive from a mansion complex of the Date clan in Matsushima, Miyagi Prefecture, Japan. It is said to have originated as a teahouse in Toyotomi Hideyoshi's Fushimi Castle, to have been moved to Edo by Date Masamune, and finally to have been brought to Matsushima by his son Date Tadamune.
