#DidYouKnow? Early in his career as daimyo of Sendai, with his sights still on a longshot bid to conquer Japan, Date Masamune set up an upper-upper-room (jōjōdan no ma) in Sendai Castle and a stable of oxen for the imperial carriage (hōren), all with the intention of receiving Emperor Goyōzei with appropriate pomp.
The room and oxen were on standby until 1868.
