About Yamagata Airport

Overview

Yamagata Airport serves the Yamagata Prefecture in northeastern Japan, located in Higashine City at an elevation of 353 feet MSL. The medium-sized airport provides critical regional aviation infrastructure, connecting the mountainous Tohoku region with other parts of Japan. Its single runway (01/19) spans 6,560 feet and is constructed with asphalt surfacing.

Flying Conditions

Weather conditions at Yamagata Airport demonstrate significant variability, with Visual Flight Rules (VFR) prevailing approximately 69.2% of the time. Pilots can expect predominantly northerly winds averaging 6.5 knots, with occasional gusts up to 23 knots. Temperature ranges from -6°C to 30°C, with an average of 9°C, suggesting potential for significant thermal variations throughout the year.

Notable Features

The airport's geographical position in the Tohoku region implies proximity to mountainous terrain, which could introduce complex wind patterns and potential turbulence. The consistent northerly wind direction and low average crosswind of 3.1 knots suggest relatively stable approach conditions. Seasons significantly impact flying conditions, with September, October, and November representing the most favorable VFR months.

Approach Considerations

Runway 01/19 demonstrates 100% favorable wind alignment, providing consistent approach opportunities. With an average crosswind of only 3.1 knots, pilots can expect predictable landing characteristics. Visibility averages 10 statute miles, with minimal occurrences of restricted visibility (fog present only 6.1% of observations).
