Oshima, with 40 years of experience in the aviation industry and former leader of Japan Airlines, became chairman of the struggling local Vietnamese airline on June 21. But he resigned two weeks later and took the vice chairman position.
Le Thai Sam, a big shareholder of Bamboo Airways, took over as chairman.
Two other board members, Doan Huu Doan and Tran Hoa Binh, are also set to be dismissed from the company at the meeting Friday.
Doan joined Bamboo Airways in the middle of last year, while Binh joined at the same time with Oshima in June.
Lastly, the Friday meeting will select one new member to join the board, while shareholders will also dismiss three members of the Supervisory Board and replace them with three new ones.
