Okadama was constructed between 1942 and 1944 as an airfield for the Imperial Japanese Army. Following Japan's surrender to the United States in 1945, ending World War II, the United States Army Air Forces took over the airfield, using it as a training base until the end of the US occupation in 1952. Following the occupation, the field reverted to the Japan Self-Defense Forces.[4]
Scheduled civilian passenger operations began in June 1956 when North Japan Airlines (later Japan Domestic Airlines, Toa Domestic Airlines and Japan Air System) began service to Memanbetsu. All Nippon Airways began service to Okadama in 1966.[4] These airlines operated propeller service at the airport through the mid-1970s, chiefly using NAMC YS-11 turboprops. Although the airport's main runway was extended from 1,000 to 1,500 m in 1967, most scheduled traffic migrated to New Chitose Airport which was better equipped to handle larger jet aircraft.[5] In 1974, Toa ceased operations at Okadama and ANA established a new subsidiary, Air Nippon, to handle YS-11 flights at the airport. ANA later replaced its YS-11s with quieter Bombardier Dash 8 turboprops.
In 1995, the city of Sapporo proposed extending the runway to 2,000 m in order to allow jet service at Okadama. This plan met protests from neighboring residents, and was abandoned in 1996. In 1998, local residents agreed to an extension of the runway to 1,500 m in exchange for a cap of 44 daily takeoffs and landings.[5]
ANA, which accounted for 80% of passenger traffic at Okadama, ceased Okadama operations in 2010, leaving JAL affiliate Hokkaido Air System as the airport's only scheduled carrier.[5] The airport terminal (operated by a company 26% owned by the Sapporo government) operated at a slight profit until fiscal year 2009, but the departure of ANA group traffic drove its finances into a net loss.[6] HAC continues to serve the airport using Saab 340 turboprops which have since been replaced by the ATR 42.
In November 2013, Fuji Dream Airlines operated a regional jet charter to Okadama from Komaki Airport in Nagoya, the first passenger jet service in the airport's history.[5]
In July 2023, Sapporo City officially announced that it would extend the runway to 1,800 meters, with the understanding of local residents.
