Source-derived summary

National Route 112 (国道112号, Kokudō Hyaku jūnigō) is a national highway of Japan that traverses the prefecture of Yamagata in a southeast–northwest routing. It connects the prefecture's capital city, Yamagata in eastern Yamagata Prefecture to the city of Sakata on the prefecture's western coast. It has a total length of 139.2 kilometers (86.5 mi).

Route description

National Route 112 begins at a junction with National Route 13 and National Route 48 in Yamagata Prefecture's capital city, Yamagata in the eastern part of the prefecture. The highway passes through Yamagata's city center. A part of this National Route 112 in central Yamagata is closed to auto traffic during the annual Yamagata Hanagasa Festival and is utilized as a part of the primary venue for the festival. After passing through the capital city's central district, the highway curves to the northwest, passing through the town of Nakayama on the way to the city of Sagae. The highway bypasses the city's central district, traveling along the eastern and northern edge of the city. On the western fringe of Sagae the highway shares a brief concurrency with National Route 458. In the city of Tsuruoka, the highway shares concurrencies with National Route 345 and then National Route 7.

Editorial summary

The public source identifies “Japan National Route 112” as road in Yamagata Prefecture, Japan. This brief keeps that definition visible, then builds a research path around Japan, National and Route.

Editorial reviewA practical starting point whose main value is the path it opens into stronger specialist and primary sources. The current 204-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The selected authority fields contribute no independent date. Its value is orientation rather than verdict, with Japan, National and Route providing the first useful test.
