|Name Kanji||前田 登美子 Maeda Tomiko|
Tomiko Maeda is Iwao's wife, Isami's mother, and Motoko's mother-in-law. She is judgemental, harsh, and verbally (sometimes physically) abusive towards people, especially Motoko. She is constantly bragging about Iwao's health before and after his death. However, Toshio points out that if she had sent him to the hospital in the first place, then his death would not have come to pass. Enraged, she takes it out on Motoko for nagging him about his health and blames her for his death. She later dies after Shihori with Motoko brutally beating her (Tomiko) in fury for denying the help her little girl needed.
