Senju Soka Highway Airfield

Not applicable, as it was almost certainly never an 'open' airport. The concept of a designated highway airstrip at this specific, heavily urbanized location is unverified. The highway section at the given coordinates was completed in 2002, well after the Cold War era when such military contingency plans were most relevant.

The location at coordinates 35.783333, 139.802778 corresponds to a busy, elevated section of the Route C2, also known as the Central Circular Expressway (中央環状線), part of the Shuto Expressway system in Adachi, Tokyo. It functions exclusively as a major public highway, carrying a very high volume of daily traffic.

There is no verifiable historical significance. The entry for 'Senju Soka Highway Airfield (JP-1298)' is considered a data ghost or a misinterpretation. While the Japan Self-Defense Forces (JSDF) had contingency plans for using roads as emergency runways (a common Cold War strategy), there is no public record or evidence that this specific section of the Shuto Expressway was ever designated for this purpose. It was never used for any known aviation operations.

None. As the site is not a former airfield but a critical piece of Tokyo's transportation infrastructure, there are zero prospects or plans for it to be converted or used for aviation purposes. Its use as an emergency strip is logistically impossible due to immense traffic, urban density, and infrastructure not designed for aircraft.
