In her one appearance, it was shown that Tamako greatly resembled her son in appearance. She had slightly long messing light color hair that was a different shade at the top. She wore the Restaurant Yukihira cooking uniform and an apron around her waist. Like her son, she would wear a white headband around her forehead when she cooked and usually kept it around her neck when she wasn't.
Tamako was the daughter of diner chefs. In spite of that, she was a horrendous cook.
Tamako was a lot like her son; she was optimistic, cheerful and sociable, making her quite popular despite her terrible cooking. She never let her failure bring her down and always tried to learn from her mistake. Both her husband and son greatly admirred this trait about her, with the former being impressed that she could come up with ideas even he couldn't think of.
- Tamako (珠子), using the kanji for "Jewel" or "Gem" (珠 Tama) and "child" (子 Ko). Yukihira (幸平), using the kanji for "blessing" (幸 Yuki) and "common" or "ordinary" (平 Hira), could translate as "blessing of the ordinary".
