In the English version, he is voiced by David Greenlee.
In the Japanese version, he is voiced by Hiroaki Hirata.
Despite his tough, strong appearance (he is noted for being an heavy smoker), he is a loving, friendly person who cares deeply about his sons. The divorce affected him a lot, he carries an old picture of the united family in his wallet. He and Matt have similar personalities and seem to understand each other quite well.
One of the running jokes in the series is that Matt considers themselves as "two single men being roommates" and he looks after Hiroaki as if they have switched roles in the family. He apparently has a soft spot for his younger son, T.K.
He works as a reporter at Fuji TV and tends to be a workaholic, but has a nice demeanor. He finds out about his sons' connection to the Digimon during Myotismon's invasion.
