Odashukuno Seaplane Base

The facility, historically known as the Imperial Japanese Navy's Miyazu Naval Air Group, was closed and dismantled following Japan's surrender at the end of World War II. Its closure was part of the nationwide demobilization of the Japanese military.

The specific coordinates (35.55985, 135.2512) point to an open water area within Miyazu Bay (Miyazu-wan), which was the operational water runway for the former base. There are no visible remnants of the seaplane base at this exact location. The surrounding land in the Odashukuno district and other parts of the Miyazu coastline is now used for civilian purposes, including residential areas, fishing ports (like the Odashukuno Fishing Port), and tourism-related facilities. The area is known for its scenic beauty, including the nearby Amanohashidate sandbar.

The designation 'Odashukuno Seaplane Base (JP-2040)' is an unofficial, modern identifier likely originating from flight simulator scenery or non-governmental aviation databases. The actual historical site was the Miyazu Naval Air Group (宮津海軍航空隊), an Imperial Japanese Navy seaplane base established in 1943 during WWII. Its primary mission was the training of seaplane pilots and aircrews. It operated various training floatplanes, such as the Yokosuka K5Y (Type 93 Intermediate Trainer) and Mitsubishi F1M (Type 0 Observation Seaplane). The base was located within Miyazu Bay, utilizing the calm waters for takeoff and landing, with land-based facilities spread around the coastline. The base was operational until the end of the war and was targeted by US Navy aircraft in July 1945.

There are no known official plans or credible prospects for reopening a seaplane base at this location. While seaplane tourism has been discussed for other regions in Japan, there have been no specific announcements or proposals from the Miyazu city government or the Kyoto prefectural government regarding the re-establishment of aviation activities in Miyazu Bay.
