context_page_description: Iruma Air Base is a Japan Air Self-Defense Force base located in the city of Sayama, Saitama Prefecture, north of western Tokyo, Japan.
  It was the airfield for the Imperial Japanese Army Air Force Academy until 1945, when it became Johnson Air Force base of the United States Air Force during and after the occupation of Japan.
  Currently, Iruma Air Base is home to the Air Defense Command Headquarters Flight Group. Aircraft located at the base include the U-4, NAMC YS-11, T-4, and Kawasaki C-1. Its annual air show on the November 3rd Culture Day holiday is a popular public event.
context_section_description: The Iruma Air Show is held annually on the November 3rd Culture Day. It generally takes place under clear blue skies. The event features ground displays of various military aircraft from all three branches of the Japan Self-Defense Forces and a performance by Blue Impulse, the JASDF's aerobatics team. Police department helicopters are also usually on ground display. In recent years UH-1N and C-12J aircraft of the US Air Force's 459th Airlift Squadron also visit from the nearby Yokota Air Base.
  A speaker at the 2010 air show sparked controversy when he criticized the government.
  Due to the base's proximity to Tokyo a large number of spectators attend the event each year, although numbers can fluctuate. In 2015 the attendance was approximately 200,000, in 2016 it was 130,000 and in 2017 around 210,000 people came to the event.
