Oita Miyoshi Weisse Adler was founded in 1994 by the Miyoshi Clinic of Internal Medicine and Cardiology.[1] Originally called Miyoshi Cardiology EKG, then Miyoshi Cardiology EKG Oita,[2] the team was named "Weisse Adler", meaning "white eagles" in German, for the characters "white eagle" (白鷲, shirawashi) in the name of the Seiun Shirawashi Association (青雲白鷲会) of the clinic.[3] The founder, Hiroshi Miyoshi, was the director of the hospital and was also involved in the management of the team.[4] Most of the team also worked at the hospital.[5] It originally had nine members.[2]
After placing first in the V1 League in the 2005–2006 season,[2] the franchise was promoted to the V.Premier League in 2006.[1] The team was demoted to the V.Challenge League in 2009.[6] In 2014, it represented Japan at the 2014 Asian Men's Club Volleyball Championship in the Philippines.[7] Oita Miyoshi Weisse Adler was demoted to V.League Division 2 after losing the V.Challenge match of the 2022–23 season to Voreas Hokkaido.[8][9]
In March 2024, the founder died and the club had difficulty continuing operations.[4] The next month, the franchise announced the suspension of all activities and their withdrawal from the new V.League in late May as they were unable to find a company to transfer the team to.[10][1]
