The Tokaido corridor is a major urban region in which country?

• A. China
• B. Japan
• C. Korea
• D. Vietnam

Answer: (B)

The Tokaido corridor refers to a highly urbanized belt along the Pacific coast of Japan’s Honshu island, connecting major cities such as Tokyo, Yokohama, Nagoya, and the Kyoto–Osaka area. The name comes from the historic Tōkaidō road, the main route that linked Edo (now Tokyo) with Kyoto during the Edo period. In modern geography and urban planning, this corridor is known as one of Japan’s largest metropolitan regions, sustained by dense population and a powerful transportation network, including the Tokaido Shinkansen. That’s why the major urban region described is in Japan. It’s not located in China, Korea, or Vietnam, which have their own distinct urban corridors.
