About JASDF Shizuhama Air Base

JASDF Shizuhama 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 Shizuhama Air Base is a medium-sized military airport located in Yaizu, Japan, situated at 23 feet above mean sea level. The base serves Japanese Air Self-Defense Force operations and is positioned near the Pacific coast with coordinates 34.812801, 138.298004. Its single runway 09/27 spans 4,920 feet with an asphalt surface.

Flying Conditions

Weather observations indicate predominantly favorable flying conditions, with 66.2% of recorded periods supporting VFR flight rules. The prevailing wind comes from the northeast at an average of 7.8 knots, with temperatures ranging from 2°C to 33°C and an average of 18°C. Pilots can expect excellent visibility, with an average of 10 statute miles and minimal instances of reduced visibility or fog.

Notable Features

The airport's coastal location near Yaizu suggests potential for maritime weather influences and thermal variations. Runway 09/27 demonstrates 100% wind favorability, meaning wind conditions are consistently aligned with runway orientation. The relatively low elevation and flat coastal terrain provide straightforward approach and departure profiles for aircraft.

Approach Considerations

With a consistent northeast wind averaging 4.1 knots of crosswind, pilots should anticipate stable approach conditions on runway 09/27. January, November, and December offer the most reliable VFR conditions based on historical meteorological data. The airport's geographical positioning and wind patterns make it a predictable and manageable destination for most aircraft operations.
