Seki Heliport

Primarily economic reasons. The heliport, operated by Seki City, had an extremely low utilization rate since its opening. For example, in fiscal year 2008, there were only two recorded landings. The annual maintenance and operational costs of approximately 2.5 million JPY were deemed unsustainable by the city government given the minimal use. The application for abolition was officially approved by Japan's Ministry of Land, Infrastructure, Transport and Tourism (MLIT) on March 26, 2010.

The site has been repurposed by Seki City and is now the location of the Seki City Disaster Prevention Center (関市防災センター). The helipad markings have been removed, and the large paved area is used as a staging ground, training area, and parking lot for the center. While the open space could likely accommodate a helicopter in a major emergency, it is no longer a registered or maintained heliport.

Seki Heliport, officially known as Seki Public Heliport (関公共用ヘリポート), opened on April 1, 1996. It was established by Seki City as a public-use facility. Its intended purpose was to serve as a vital hub for disaster prevention, emergency rescue operations, and emergency medical transport (such as for the 'Doctor Heli' service) in the region. It was also envisioned to support local industry and tourism. Despite its strategic location near the Tokai-Hokuriku Expressway and the Nagara River, it never achieved significant operational traffic during its 14 years of service.

There are no known plans or prospects for reopening Seki Heliport. The fundamental reasons for its closure—lack of demand and high operational costs—have not changed. The site has been permanently and effectively repurposed into a ground-based disaster management facility, making a return to a certified aviation facility highly unlikely.
