Officially the road is designated as Aichi Prefectural Route 7. The road is designated (motor vehicles must have a displacement of at least 125 cc), and the design standard of the road is similar to
national expressways. The road connects the southern portion of the
Chita Peninsula with
Nagoya through the
Chitahantō Road. A toll plaza formerly separated these two roads since the Chitahantō Road was administered by
Japan Highway Public Corporation, however since the administration of that road was transferred to Aichi Prefectural Road Public Corporation the toll plaza has been abandoned and a unified toll structure has been implemented. ==Interchange list==
