Schrott,
In Goshogawara-shi, here is a possibility:

It is The Patio Sunroute Hotel. I once stayed there when the prefectural government put me up in it for a bit over a week and a half. It is a very basic, small "business hotel" type accomodation. Nothing fancy, but clean and centrally located in the the town.
Not much English though. (I speak a bit of "survival" Japanese.) But probably enough that you could make do without it.
best,
