On July 16, 2021, Yasunami was appointed to the Supreme Court of Japan. In Japan, justices are formally nominated by the Emperor (at that time, Naruhito) but in reality the Cabinet chooses the nominees and the Emperor's role is a formality.^[2]

Yasunami's term is scheduled to end on April 18, 2027 (one day before he turns 70). This is because all members of the court have a mandatory retirement age of 70.^[2]
