Kondo participated in four Division I International Ice Hockey Federation world championship tournaments between 2001 and 2013, with Japan placing second in 2001 and 2005, first in 2007, and fourth in 2013. She plays as a defenseman with the Seibu Princess Rabbits in the Japan Women's Ice Hockey League, while also employed professionally as an office worker. In January 2014, Ilzuka Yuji, head coach of the Japan women's national ice hockey team, played Kondo as a forward in a friendly match and found her speed, body size and powerful shots suited her for the role. Yuji decided to play Kondo as forward in the 2014 Winter Olympics, although she only started seriously training in the position in December 2013.
