Mr. Tachibana is a tall middle-aged man of average stature with short, brown hair and brown eyes. He wears eyeglasses without frames.
Mr. Tachibana seems to be a calm, level-headed, loving man who always listens to what people have to say. He is well informed, knowing that the swimming club Makoto used to go is finally being torn down. He is supportive of his son's aspirations and, along with the rest of the Tachibana family, is seen attending one of Makoto's tournaments. He also provides for tuition and expenses once Makoto moves to Tokyo in order to attend university.
It seems that Mr and Mrs Tachibana aren't the kind of couple who argue often, if at all. They seem happily married and in love with one another from what is seen of their interactions. Makoto and his dad have a great relationship as they are frequently seen talking together and relating well. Ren and Ran also have a good relationship with their father.
- Mr. Tachibana's former English voice actor, Jerry Jewell, also provides the voice for Momotaro Mikoshiba.
