Hi, I'm planning to go to Sendai around autumn. I live in Ibaraki, so I'm planning to go up the coast and come back on the highway.
Emijah, I hear ya. Riding in Autumn is just brilliant. October is defintely one of the best months to be on a bike here. Look into the Rikuchu Kaigan run. Route 45 that runs north out of Sendai.
Thanks for your encouraging comments and interest everyone.
