Nakaisaido Heliport

The closure was due to economic and operational reasons. Nakaisaido Heliport was not a public airport but a private 'off-aerodrome landing site' (場外離着陸場 - jougai richakuriku-jou) associated with the industrial facility at the location. The company operating the site likely discontinued helicopter operations as they were no longer cost-effective or necessary for their business, which is focused on ground-based logistics. The heliport was an ancillary asset, not a core business.

The site is currently occupied by the SBS Logicom Nakai Sales Office (SBSロジコム 中井営業所), a major logistics and warehousing company. The original helipad, a paved area with a faint, weathered 'H' marking, is still visible on satellite imagery. However, it is no longer maintained or used for aviation. The area is now integrated into the logistics center's grounds, likely used for vehicle parking or maneuvering.

The heliport held no major historical significance in Japanese aviation. It was a private utility heliport built to serve the specific needs of the business operating the adjacent warehouse and logistics center. Its operations would have been limited to corporate transport for executives, client visits, or potentially the rapid transport of small, high-value goods. The ICAO code JP-2311 was an identifier for this private landing site within the Japanese aviation system but does not imply it was open to public use.

There are no known plans or prospects for reopening the Nakaisaido Heliport. The current owner, SBS Logicom, is a ground and sea logistics provider, and helicopter transport does not align with their primary business model. Given the site's full conversion to a high-capacity logistics center and the years of disuse, the likelihood of the heliport being reactivated is effectively zero.
