The Aqua Wing Arena was constructed as Venue B for the ice hockey events at the 1998 Winter Olympics, and was the last venue to be completed for the Games, in September 1997.[1][2]Big Hat, the principal Venue A for the ice hockey competition at the 1998 Winter Olympics, is located approximately 5.3 km southwest of Aqua Wing Arena. M-Wave, the site of the speed skating events at the Games is located approximately 2.5 km south of Aqua Wing Arena.
The Aqua Wing Arena was designed to be converted into an aquatics centre, and the retrofit was completed in 1999.[3] The arena consists of a 50-meter pool, a 25-meter swimming pools, and a diving pool.[a 2] The roof is retractable. Although the arena sat 6,000 during the 1998 Winter Olympics, the civic pool currently seats 2,000 spectators.[4] The Aqua Wing Arena will be an international pre-training camp for the 2020 Summer Olympics.[5]
Construction and equipment

The design of Aqua Wing Arena includes sharp flowing lines which represent the wind and water of the region. [a 3] Its name, Aqua Wing derives from its similarity to a wing. [a 4] Its retractable roof is supported by V-shaped pillars.[a 5]
Aqua Wing Arena was built on public land in Nagano Sports Park, as such land costs for the venue were nil; however, construction costs for the arena totaled 9.1 billion yen.[a 6] The venue covers an area of approximately 5.2 ha.[a 7] The permanent facilities include a building area of approximately 10,100m2, with total floor area of approximately 13,500m2.[a 8] The building is made of reinforced concrete and steel frames, with three stories above ground and one below rground.[a 9] The maximum height of the building is 31m. [a 10] In addition, 16 temporary structures covering 2,390m2 and providing 4,690m2 of floor space were built.[a 11]
To build the ice for Aqua Wing Arena, a temporary rink was situated on top of the 50-meter pool and diving pool, with indirect ammonia refrigeration.[a 12] The ice hockey rink was built to International Ice Hockey Federation standards, 60m x 30m.[a 13] Sound dampening measurers were used because the ice hockey rink was built atop an empty space.[a 14] The 25-meter pool was used for the sub press center.[a 15] Aqua Wing Arena was the only venue at the 1998 Winter Olympics that did not stage international competitions before the Games.[a 16] In lieu of international competitions, several Japan Ice Hockey League matches were held which permitted staff and volunteers to practice procedures.[a 17]
Electricity for the Aqua Wing Arena during the games was generated by gas engines, and heat generated by the engines and freezing equipment was used as energy for the heating system.[a 18] This system resulted in capturing 80% of the heat generated by the engines and freezing equipment.[a 19] This system is used to heat the swimming pool.[a 20]
