⏳ From Turboprops to Jets: A Quick History

Opened by the Wakayama Prefectural government in April 1968, the airport started small with a modest 1,200-meter runway. In its early days, it offered flights to Osaka, Nagoya, and Tokyo. Over time, regional transit shifted, and the Osaka and Nagoya routes were discontinued.

To future-proof the airport, a brand-new 1,800-meter runway was built on adjacent land in 1996 specifically to handle modern jet aircraft. That runway was later extended to 2,000 meters, ensuring smooth landings for commercial jets. Today, private management company Nanki-Shirahama Airport, Inc. keeps operations running smoothly.

♨️ The Tourist Advantage: Why Travel via SHM?

Geographically, the airport sits about 65 kilometers south-southeast of Wakayama City. Because the massive Kansai International Airport (KIX) opened closer to the city center in 1994, Nanki-Shirahama Airport pivoted to do what it does best: serve as a paradise portal for vacationers.

The airport drops you just 1.5 kilometers outside the center of Shirahama Town. This makes it the ultimate landing pad for tourists flocking to the famous Nanki-Shirahama Onsen resort area, Adventure World, and the rugged, sacred landscapes further south along the peninsula.
