Nanki Shirahama Airport — Shirahama, Japan

Nanki Shirahama Airport, coded SHM, is located in Wakayama Prefecture on Japan's Kii Peninsula, serving the popular hot spring resort town of Shirahama. The airport offers regular flights to Tokyo's Haneda Airport, making it a convenient access point for visitors to the region's renowned onsen baths, white sand beaches, and coastal scenery. SHM's compact terminal and single runway reflect its role as a regional leisure-travel airport rather than a major transit hub. Shirahama has long been considered one of Japan's oldest hot spring destinations, and the airport plays a central role in sustaining tourism to this coastal area, particularly during peak holiday and summer travel seasons.
