Bereaved relatives of a mother and a daughter killed by a runaway car in Tokyo's busy Ikebukuro district about five years ago met with the 92-year-old perpetrator for the first time Wednesday at the prison where the convict is detained.

Takuya Matsunaga, 37, who lost his wife Mana, 31, and daughter, Riko, 3, in a high-profile accident on April 19, 2019, told reporters after the visit that he hopes the perpetrator's words can provide "hints" on how similar incidents can be prevented.

Matsunaga and Mana's father, Yoshinori Uehara, 66, met with the inmate, Kozo Iizuka, who was the head of the now-defunct Agency of Industrial Science and Technology under the Ministry of International Trade and Industry, now the Ministry of Economy, Trade and Industry.
