About Kagoshima Airport

Overview

Kagoshima Airport serves as a critical transportation hub for southern Kyushu, located in Japan's Kagoshima Prefecture. Positioned at an elevation of 906 feet mean sea level, the airport supports commercial, cargo, and general aviation operations with its substantial single runway measuring 9,840 feet in length.

Flying Conditions

Situated at 31.803400°N latitude, Kagoshima Airport experiences typical maritime subtropical climate conditions characteristic of southern Japan. Pilots should anticipate potential seasonal wind variations and precipitation patterns that can influence approach and departure procedures, particularly during summer typhoon seasons and winter monsoon periods.

Notable Features

The airport's terrain is influenced by its proximity to volcanic regions, with potential for unique meteorological interactions due to local geographic conditions. The single runway (16/34) is constructed of asphalt, providing a robust surface for diverse aircraft operations at this elevation.

Approach Considerations

Given the runway's 16/34 orientation, prevailing wind patterns will significantly influence approach and landing strategies. Pilots should carefully assess current meteorological conditions and utilize standard instrument approach procedures, maintaining awareness of the airport's 906-foot elevation when calculating performance parameters.
