Kazuki Miyamoto Wiki – Kazuki Miyamoto Biography
Kazuki Miyamoto, 37, is accused of killing 21-year-old college student Hinako Hamano last October by spiked her drink with thallium. Thallium was also recently found in her female relative, who has been in a coma since 2020, local media reported, citing sources.
Just 1 g could kill an adult. But the police have not found a motive, nor how she had gotten her hands on the poison. The suspect was arrested on March 3 in Kyoto. Thallium is a soft metal that dissolves in water and has no taste or odor, making it difficult to detect outside of a laboratory.

Accused of killing Hinako Hamano with thallium
It is believed that Mr. Miyamoto, a real estate agent, administered thallium to Ms. Hamano sometime around October 11 and 12 when she visited her apartment in Kyoto. He had told police that the two were out for dinner on the night of October 11 before heading to Ms Hamano’s home for a drink, the Japan Times said, citing investigators.
According to Mr. Miyamoto, Ms. Hamano experienced severe coughing fits. She then contacted her family, who took her to a hospital the next day. Hamano died on October 15 of severe respiratory failure: thallium was found in her vomit and urine, the Asahi Shimbun reported.
The police suspect that Mr. Miyamoto had drugged Ms. Hamano’s drink when they were alone in her apartment. While analyzing Miyamoto’s smartphone, police found Internet searches for thallium from before Hamano’s hospitalization.
Miyamoto and Hamano seemed happy in each other’s company
Local media reported that Hamano first met Miyamoto through a part-time job. In addition to his real estate business, Mr. Miyamoto also runs an entertainment-related business involving maikos, or apprentice geishas. “Miyamoto and Hamano sometimes drank and dined together, and seemed happy in each other’s company,” the Asahi Shimbun said, citing acquaintances. A relative of Mr. Miyamoto’s, who has been hospitalized in Kyoto since July 2020 and is now unconscious, was also found to have ingested thallium. The Mainichi reported that this relative is over 60 years old and suddenly collapsed around the summer of 2020.
The substance is strictly regulated in Japan. In most cases, researchers or companies buy it from specialized companies. In 2015, a Nagoya college student was convicted of attempting to murder two classmates with thallium while she was in high school. The same chemical had been used in lethal doses by the Islamic State group on her prisoners.
