About Sendai Airport

Overview

Sendai Airport is a significant international airport located in Natori, Miyagi Prefecture, Japan. Serving the Sendai metropolitan area, this large airport operates at an elevation of 15 feet above mean sea level. Its strategic location and two asphalted runways make it an important transportation hub for the Tohoku region.

Flying Conditions

The airport's low elevation of 15 ft MSL suggests minimal terrain-related weather challenges. Situated at coordinates 38.139702, 140.917007, Sendai experiences typical maritime climate conditions characteristic of northern Japan. Pilots should anticipate potential seasonal variations in wind and visibility that are common to coastal airport environments.

Notable Features

Sendai Airport features two runways: a primary 9,842-foot runway (09/27) and a secondary 3,940-foot runway (12/30), both constructed with asphalt surfaces. The dual-runway configuration provides operational flexibility for different wind conditions and aircraft types. Its coastal location near 38°N latitude indicates potential for complex local meteorological interactions.

Approach Considerations

The runway orientation (09/27 and 12/30) offers multiple approach options depending on prevailing wind conditions. The substantial length of the primary runway (9,842 ft) accommodates a wide range of aircraft types and provides ample landing and takeoff capabilities. Pilots should carefully assess wind direction and runway conditions when planning arrivals and departures.
