There are two ways to get get to places in Iwate Prefecture. You can use Route 45 and take the scenic coastal road or you can go down the Hachinohe Expressway to the Tohoku Expressway. These instructions take you via the Expressway. You would be better off using this route to get to Morioka City, Nango, Kenji World, etc as well as some of the more popular ski slopes.
Exit the base from the POL gate and proceed straight about 3 KM until you reach the Momoishi Toll road. It is the first overpass you will come to.
Turn left at the traffic light just prior to the overpass and you are on the entrance ramp to the toll road. As you get on the bypass, set your trip counter.
You will pass through the Shimoda Toll Gate (¥200) and continue on past the Shimoda and Hachinohe Kita exits.
Follow this highway as it turns seemlessly into the Hachinohe Expressway and then into the Tohoku Expressway.
You can pick up the instructions below for the specific destination you are looking for.......
Morioka Handiworks Square
Get off the Tohoku Expressway at the Morioka Minami IC. You will have travled about 140KM from where you entered the Michinoku Bypass in Shimoda. There is a JUSCO mall on the left that you can clearly see as you approach the exit.
The last time I checked, the toll was ¥3650.
Take the right fork on Route 46 heading towards Akita.
Follow Route 46 for about 6.5 until you come to a stop light with a Camel Mart on the left side and a Sunkus on the right.
Turn left at this light.
You will pass a wooden sign on the left that says "Morioka Handi-Works Square".
If you were to continue on along this road, you would get to Kenji World.
