Japan National Route 357

Japan National Route 357 is a national highway that extends approximately 88 kilometers along Tokyo Bay, connecting multiple urban districts through Chiba Prefecture and the Tokyo metropolitan area. The road passes through a dense network of residential, industrial, and commercial areas with several elevated sections and connections to other major routes.

This national road was established in 1975 by the Ministry of Land, Infrastructure, Transport and Tourism as part of Japan's highway expansion system. It was designed as a crucial north-south corridor to support rapid growth in the Tokyo Bay region.

The road links residential areas with industrial zones and commercial centers, shaping daily routines for many commuters in the region. It serves as a vital connection for people moving between Chiba and Tokyo.

Drivers can find multiple rest areas and service facilities along this route, as well as connections to other major roads including Route 14. Travel conditions vary by time of day and traffic volume, so be prepared for heavier congestion during rush hours.

Several sections of this route are built as elevated highways, offering views of Tokyo Bay while driving. This perspective makes it an interesting alternative to parallel roads in the region.
