Chinese Taipei Football Association
In November 2005, Imai was appointed by Japan Football Association to coach Chinese Taipei national team and to help the football development in Taiwan. It was his first international assignment. He accepted the challenge and signed a one-year contract with Chinese Taipei Football Association in December. Under his guidance, although the team did not have any amazing performance in international competitions, it was believed that Imai did bring good influence on the team, as well as football activities in Taiwan.
