Ryūgasaki Airfield
airport
Ryūgasaki Airfield (竜ヶ崎飛行場, Ryūgasaki Hikōjō) is a privately owned airfield in the city Ryūgasaki, Ibaraki, Japan.
The airport was opened on November 11, 1969, as a private venture by Nissho Iwai. Although there are no scheduled flights, it is a base for light aircraft and pilot training. Due to its proximity to Narita International Airport, the airspace around the airport is under traffic control by Narita, and there are certain restrictions on operations. The runway is also used as a drag racing course.
The airport contains the headquarters of New Central Airservice.
Begin with the source’s own compact description: “Ryūgasaki Airfield” is airport. The dossier treats that line as a proposition to test through Ryūgasaki, Airfield and airport, not as a finished interpretation.
Why this record matters
The phrase “airport” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Place names and jurisdictional language are key evidence: both can reveal earlier catalogue descriptions and overlooked record series. The source revision retrieved here is dated Jul 7, 2026. The linked authority identifier is Q1447375. Authority coordinates are 35.906, 140.242. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1969.
A single description cannot reconcile every naming convention, rebuilding phase or administrative transfer associated with a place. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
