Mrs. Tamura is a woman of advanced age and short stature, with gray hair tied up in a bun and secured beneath a kerchief. Her eyes are difficult to see due to wrinkles. In her singular appearance, she's seen wearing a blue kimono and likely a tan haori that can't be seen properly because of her long-sleeved white apron, green socks and straw zōri. She carries a straw basket. Her outfit gives an impression of an older traditional Japanese woman.
Mrs. Tamura is a calm, soft-spoken person who looks out for others, as seen by her gesture of giving Makoto Tachibana food before he goes to school.
Mrs. Tamura's only contribution to the story is to stop Makoto as he makes his way from home towards Haruka Nanase's house at the top of the stairs. She is his neighbor and stops him in order to give him some food, which he graciously accepts. As a much older character, she provides immediate contrast between the physical stature of her generation and that of Makoto and his comrades.
Mrs. Tamura is a close neighbor of the Tachibana family. She appears to be on good terms with them, as evidenced by her friendly demeanor towards Makoto.
