The roadside station "Shizukuishi Anekko" is located by National Route 46 near the border between Iwate and Akita prefectures, about 30km west of the center of Morioka City. It has a variety of facilities including a hot spring, an auto camping ground, a dog park, a herb greenhouse, and a soba restaurant is attached.
You can camp, take hot spring, and there is a dog park. I couldn't wait for the park to open in spring, so I and Sachiki-san went to check it out (lol)
