Insider tip — Asu no Yu, the Tomorrow Hot Spring, expresses hopeful renewal at the edge of the great city of Date Masamune, the one-eyed dragon lord who built Sendai in 1601 as the most sophisticated regional capital in eastern Japan. Today Sendai is the metropolis of Tohoku, celebrated for the Tanabata star festival whose paper decorations fill the arcade streets each August, and for the distinctive gyutan beef tongue cuisine that defines the city culinary identity.
