In the competition, Kotani earned two bronze medals: one in the solo synchronized swimming event and another in the duet event, where she partnered with Miyako Tanaka Urabe. Following her Olympic success, she was honored with several prestigious accolades, including the Tokyo Metropolitan Citizens' Honorary Award, the Big Sports Award, and the Prime Minister's Silver Cup.

Following her impressive performance at the 1991 World Championships, Mikako Kotani announced a temporary break from professional swimming. During this hiatus, she became actively involved in the bid activities for the 1998 Winter Olympics in Nagano, Japan.

Her strong record and previous Olympic achievements earned her a spot on the Japanese Olympic team for the second consecutive time, making her the first Japanese synchronized swimmer to participate in two successive Olympic Games. Leading up to the Barcelona Olympics, there was intense internal competition for the solo and duet spots, with Kotani competing against talented swimmers such as Fumiko Okuno and Aki Takayama. Although Kotani and Takayama were initially announced for the duet event, a last-minute change saw Okuno and Takayama compete instead.
