Ikegami was born on August 29, 1951, in Japan. He attended Tohoku University and graduated with a degree in Law in 1975. Ikegami spent over 35 years serving as a public prosecutor in various offices in the Japanese government before his appointment to the Supreme Court in 2014.

Supreme Court
On October 2, 2014, Ikegami was appointed to the Supreme Court of Japan. In Japan, justices are formally nominated by the Emperor (at that time, Akihito) but in reality the Cabinet chooses the nominees and the Emperor's role is a formality.

Ikegami's term ended on August 28, 2021 (one day before he turns 70). This is because all members of the court have a mandatory retirement age of 70.
