Take a hot spring break on National Route 7
Whether traveling from Ikarigaseki IC toward Odate or from Odate-kita IC toward Aomori, combine a toilet break, meal, and bath. On a long drive, the hot spring makes this a more restful stop.
National Route 7 → toilets and lunch at the roadside station → day-use bath → depart.
Snow and fog can change road conditions on the pass. Leave extra travel time in winter.
