Sakimura played the cimbalom part in the 2007 Matsumoto concert, which was broadcast live on NHK’s BS hi-vision service.

On August 2, 2017, Sakimura appeared as the cimbalom-playing guest on BS Japan’s Ongaku Kosaten, performing Albert Péch’s Sonnet No. 4 for solo cimbalom and movements from Bartók’s Romanian Folk Dances with violinist Yasuko Ohtani. Her 2019 album DIVERTIMENTI – Marimba Alive! vol.2 includes all three movements of Seiji Yokoyama’s Divertimento for Two Marimbas, Kiyukyoku, performed with Moyuru Oda. In November 2024, Sakimura performed at the 17th World Cimbalom Congress in Seoul and served on the jury of its international competition.
