@darnell Stay in Sendai. It's a beautiful, modern city full of nice people. Close enough to Tokyo if you need to get there, but far enough to avoid, well, Tokyo. Also close to Akita. (When I say close, I mean shinkansen-close.)
If you're planning to go West, I'd recommend staying in Hiroshima. You can easily reach Kansai and Yamaguchi from there, and visit Miyajima. It also has great bookstores.
