Tsukishima Airfield

Not Applicable. The airport is considered a fictional or erroneous entry in unofficial aviation databases. There are no historical records of its operation or closure.

The specified coordinates (35.652659, 139.777924) point to the middle of a highly developed, dense urban neighborhood in the Kachidoki district of Chuo, Tokyo, adjacent to Tsukishima. The area is characterized by numerous high-rise residential towers, commercial buildings, schools, and public parks. There is no trace or available space for an airport or runway.

Tsukishima Airfield (JP-1378) has no historical significance as there is no credible evidence that it was ever a real-world aviation facility. Key points supporting this conclusion are:

1. **Invalid ICAO Code**: The code 'JP-1378' does not follow the standard ICAO format for Japanese airports, which begin with 'RJ' (e.g., RJTT for Haneda). This type of code is commonly found in non-official databases, often used for flight simulators, which may contain user-generated or erroneous data.
2. **Lack of Historical Records**: Extensive searches of Japanese historical archives, aviation history records, and period maps show no mention of an airfield or airport on the island of Tsukishima. While there was a nearby Tsukiji Naval Air Base in the 1930s, it was located in a different area (where the former Tsukiji Fish Market stood).
3. **Geographic Implausibility**: The Tsukishima area was created through land reclamation in the late 19th century and was primarily developed for industry and housing. While open spaces existed, there is no record of one being commissioned as a formal airfield.

None. As the airport never existed, there are no plans or prospects for it to open or reopen.
