About JASDF Hamamatsu Air Base

JASDF Hamamatsu Air Base is a military facility. Civilian access may be restricted or require Prior Permission (PPR). Pilots should consult the JP AIP for current access procedures and restrictions.

Overview

JASDF Hamamatsu Air Base is a medium-sized military airport located in Hamamatsu, Japan, serving the Japan Air Self-Defense Force (JASDF). Situated at 150 feet above mean sea level, the base is positioned at coordinates 34.750198, 137.703003, providing strategic aerial capabilities in the central region of Japan.

Flying Conditions

The airport's elevation of 150 ft MSL suggests a relatively low-altitude environment with potentially moderate atmospheric conditions. Pilots should anticipate typical coastal maritime influences given the airport's geographic location, which can introduce variable wind patterns and potential visibility challenges.

Notable Features

The primary runway 09/27 measures 8,366 feet in length, constructed with concrete (CON) surface. This substantial runway length provides flexibility for various aircraft types and operational requirements, accommodating both military and potential alternate civilian aviation needs.

Approach Considerations

Given the runway's 09/27 orientation, pilots should be prepared for approaches from either easterly (09) or westerly (27) directions depending on prevailing wind conditions. The concrete runway surface offers reliable traction and stability for aircraft operations, with sufficient length to support a wide range of aircraft landing and takeoff profiles.
