Kochi Ryoma Airport — Nankoku, Japan

Kochi Ryoma Airport, coded KCZ, serves Kochi city on the Pacific-facing southern coast of Shikoku, Japan's smallest main island. The airport's name honors Sakamoto Ryoma, a samurai from Kochi celebrated as one of the key figures behind the Meiji Restoration that ended feudal rule and modernized Japan in the nineteenth century. All Nippon Airways and Japan Airlines operate the bulk of scheduled flights, connecting Kochi primarily to Tokyo and Osaka, since Shikoku's mountainous terrain and limited rail links make air travel a practical option for reaching the capital quickly. Kochi Prefecture is known for its rivers, notably the Shimanto, often described as one of Japan's last clear-flowing waterways, along with a warm climate that supports early vegetable harvests shipped nationwide.
