Tadao Tomomatsu's hobbies are primarily related to the worlds of science fiction and mystery.

Tadao is both an avid collector and maker of props and costumes.   His primary hobby is creativity, coming up with ideas and then starting them along their precious little ways.

His most time-intensive hobby is that of being a member of Science Fiction Fandom.   In his spare time he interacts with the wide variety of personalities who attend Science Fiction Conventions and Events  (which definitely provides a large repertoire for an actor to study).   This has led to him running such events as well as being invited as a Guest of Honor to many more.
