Sugita and fellow seiyuu Narita Ken are sometimes referred to as "brothers", although no one really knows why. During an Omaera No Tame Darou event, hosts Morikawa Toshiyuki and Hiyama Nobuyuki asked Sugita how they were similar. His answer was that both of them rarely blink, making eye-to-eye contact with either a frightening encounter.
Sugita has also had a close friendship with fellow seiyuu Nakamura Yuichi since 2001.
