Takahiko closely resembles an older version of his son, Kousei Arima. He has short messy black hair, blue eyes, and wears black-rimmed spectacles.
Hiroko Seto described him as a "free-range parent" due to him always being away on business trips.
In one of Kousei's flashbacks, he is shown walking with Kousei in the hospital towards Saki's bed.
Shigatsu wa Kimi no UsoEdit
Takahiko regularly goes on business trips, leaving his son, Kousei home alone for most of the year.
