Gohei is a man in his early thirties. He never has his eyes truly open, and has a slight mustache. His hair is behind his ears, reaching some inches below them.
He is often seen in t-shirts with English phrases and jeans.
In contrast to the owner across the street regarding Mochizō as a spy whenever he comes over, Gohei welcomes Tamako and is on friendly terms with her. He prefers modern tastes, and enjoys incorporating English into his workplace.
He refers to his son as "my junior", re-named Ōji-ya Ricecake Oh! Zee, and has a product called "Love You Forever" mochi. He is seen as more laidback, though was visually upset in his son's decision to go to Tokyo to study film, turning his head dramatically and ignoring him in a manner that was perceived as childish, and vented his worries at the bar with Mamedai.
- Mamedai Kitashirakawa: They often argue with each other, something that occasionally breaks out into minor physical fights. Their contrasting views on mochi-making causes this, with Mamedai being too traditional. Despite this, Mamedai has said that he often goes out drinking with him.
- Mochizō Ōji: Mochizō is Gohei's son, and often breaks up the fights (or simply watches if it does not become physical) the latter has with Mamedai. Gohei was frustrated when learning Mochizō was moving to Tokyo to a university, giving his son the silent treatment although failed under certain circumstances. It is inferred from the incident that Gohei does love his son.
