Kamiji won doubles titles with Sharon Walraven in Pensacola, Sabine Ellerbrock in Iizuka. Ju-Yeon Park in Daegu, Jordanne Whiley in Paris and the Masters. With Ellerbrock in New York and Whiley at Wimbledon, Kamiji was the runner up.

Kamiji followed that up by winning the second Grand Slam tournament of the season at Roland Garros. Whilst partnering Jordanne Whiley during the 2014 season the pair won the Grand Slam in doubles. They finished the year by adding the Masters crown after defeating Louise Hunt and Katharina Krüger in the final. However, despite the absence of van Koot and Griffioen the pair did not go undefeated throughout the tournament as they lost to Marjolein Buis and Michaela Spaanstra during the round robin group stage.
In 2017, Kamiji finished the year as world No 1, and was named ITF Women's Wheelchair World Champion for the second time in her career.
