Tōkai-Kanjō Expressway
road that circles the greater Nagoya area in Japan

The Tōkai-Kanjō Expressway (東海環状自動車道, Tōkaikanjō Jidōsha-dō) (lit. Tōkai Ring Expressway) is a toll road in the Tōkai region of Japan. It is owned and managed by Central Nippon Expressway Company.
Naming
Officially, the route is designated as National Route 475. On some signs, the expressway is represented in Japanese as 東海環状道; this is done to prevent confusion with the Tōkai-Hokuriku Expressway.
Although the road is named as an expressway, it is not recognized as a national expressway. Officially it is a national highway for motor vehicles only (一般国道の自動車専用道路, Ippan Kokudō no Jidōsha Senyō Dōro) (motor vehicles must have a displacement of at least 125 cc). However, the design standard of the Tōkai-Kanjō Expressway is similar to most national expressways.
Overview
Once completed, the expressway will form a 160 km ring road for the Tōkai Region. It is hoped that the expressway will reduce traffic congestion, link important industrial and manufacturing centers in the region, and facilitate access to Chubu International Airport and tourist areas in rural Gifu Prefecture.

Why this record matters
The phrase “road that circles the greater Nagoya area in Japan” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Jan 22, 2026. The linked authority identifier is Q7862675.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
