About Iruma Air Base

Iruma 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

Iruma Air Base (RJTJ) is a medium-sized airport located in Sayama, Japan, situated at an elevation of 295 feet above mean sea level. The base serves the Greater Tokyo metropolitan area, positioned strategically in the Saitama Prefecture. Its single runway (17/35) extends 6,562 feet and is constructed with asphalt surface.

Flying Conditions

The airport's moderate elevation and location near Tokyo suggest variable weather conditions influenced by regional maritime and continental air masses. Pilots should anticipate potential seasonal wind variations that could impact runway 17/35 operations. The surrounding terrain and proximity to urban areas may create localized wind patterns that require careful approach and departure planning.

Notable Features

Iruma Air Base's runway orientation of 17/35 indicates a north-northwest to south-southeast alignment. The airport's geographic position near Tokyo provides accessibility to a significant metropolitan region. The 6,562-foot runway length accommodates a range of medium-sized aircraft operations with sufficient runway distance for most standard approach and landing requirements.

Approach Considerations

Approach considerations should focus on the runway's 17/35 orientation, which suggests potential crosswind scenarios depending on prevailing meteorological conditions. Pilots should carefully assess wind direction and speed when selecting runway approach. The airport's elevation at 295 feet MSL provides relatively straightforward terrain clearance for standard approach procedures.
