If you do not drive, there is a bus that brings you from Morioka Station to the foothill where Shikitei is located. From that bus stop, there is a shuttle bus that brings you to Shikitei. It is otherwise within walking distance although it can be a little cumbersome if you are dragging some luggages.
The ryokan itself is very well-maintained and clean. The service was top-notch with a staff member ready to receive you after check-in and taking the elevator to your floor and would guide you to your room.
The food was in the kaiseki-style. It was great. Absolutely no complaints.
The one downside, perhaps, is that there is nothing much to do in the area after dark. There is a convenience store that is supposedly within walking distance. Although you have to walk on a main road, it is not very well lit.
