Aichi Nagatoku Seaplane Base

The facility ceased operations at the end of World War II following Japan's surrender. The closure was a direct result of the Allied occupation's policy to dismantle Japan's military-industrial complex, which included a ban on all aircraft manufacturing. The factory and its facilities had also sustained significant damage from Allied bombing raids targeting Nagoya's industrial centers and the severe 1944 Tōnankai earthquake.

The site has been completely redeveloped and is now an integral part of the modern, heavily industrialized Port of Nagoya, Japan's largest and busiest port. The original coastline, ramps, and hangars are gone, replaced by concrete seawalls, commercial warehouses, factories, and extensive port infrastructure. There are no visible remnants of the former seaplane base. The area is used for logistics, manufacturing, and international shipping.

This was not a public airport but the private factory seaplane base for the Aichi Aircraft Company (Aichi Kokuki), a critical supplier of aircraft to the Imperial Japanese Navy during WWII. The base, associated with Aichi's Eitoku plant (the name 'Nagatoku' is likely a misreading of 'Eitoku' 永徳), was used for the final assembly, flight testing, and delivery of newly manufactured seaplanes and floatplanes. It played a vital role in the production of key naval aircraft, including the ubiquitous Aichi E13A 'Jake' and the later E16A 'Paul' reconnaissance floatplanes. Most notably, it was the development and testing site for the Aichi M6A Seiran, a unique submarine-launched attack floatplane designed specifically for the I-400 class submarines. The base was therefore a crucial component of Japan's naval aviation war effort.

Non-existent. There are absolutely no plans or prospects for reopening the seaplane base. The site is now essential and high-value industrial and port land in one of Japan's most critical economic zones. The original military purpose is obsolete, and there is no modern commercial or civil aviation requirement for a seaplane facility in this heavily congested and developed location.
