Japan National Route 103 partially coincident with Japan National Route 454
Lake Towada
The concurrency follows the Oirase River upstream until it reaches Lake Towada. At the shore of the lake, the concurrency ends with Route 102 forming the northeast and northern parts of a road that circles the lake, while Route 103 forms the eastern and southern part of the road. As the road begins to travel along the southern shore of the lake it meets Japan National Route 454 where the routes form a concurrency. Along the southern part of this circular road, Routes 103 and 454 cross into Akita Prefecture. Continuing along the lake's southern shore, the road meets the western end of the concurrency, Route 454 continues toward Route 102 as the remaining portion of the road to circle the lake while Route 103 begins traveling to the southeast.
