was the first recorded Japanese serial killer, active during the Meiji era. Named the country's first 'pistol robber', his life was later adapted into the country's first drama movie, Armed Robber Shimizu Sadakichi (1899), and then the 1930 adaptation Sadakichi Shimizu.
Shimizu was born on August 13, 1837, in Kiyoshima-cho, Asakusa, in Edo, during the Tenpà  era (present-day Taità Â, Tokyo).
By profession, he was an anma practitioner based in Tokyo City's Honjo-ku prefecture (present-day Ryà Âgoku in Sumida). At the time, his job served as good camouflage for his later crimes.
Beginning in 1882, he would mask himself and rob people around Tokyo City, killing five in the process by shooting them with a handgun. It was the first case in Japanese criminal history where a pistol was used, and it shook the capital at that time.
Immediately after breaking into a merchant's home in Bakurocho, Nihonbashi-ku (present-day Nihonbashikurocho in Chà «à Â), he was arrested at dawn on December 3, 1886. At that time, one of the arresting officers, Ogawa, was shot and seriously injured, but managed to recover and was promoted to assistant police officer second class. However, his injury worsened four months later, and on April 26, 1887, he died at 24 years of age. In September of that year, the 50-year-old Shimizu was sentenced to death and subsequently executed.
In order to honor Officer Ogawa, a bridge crossing the Hamamachi River was named after him. It was eventually dismantled by city planning, but in 1974, a stone monument was erected on the anniversary of his death.
At the time, newspapers serialized the incident in the form of reading material. A shinpa play titled "The Pistol Robber Sadakichi Shimizu" was performed in 1897, which was attended by a 10-year-old Ton Satomi.
The writer Iruru Masaoka noted in his book "History of Japanese RÃ Âkyoku" that Shigemasa Kimura, a master of the art, once sang about the story of Shimizu.
In 1899, while Koyà  Komada was producing Japan's Initiative Photo Session, he created "The pistol robber Sadakichi Shimizu", a drama movie. This became the country's first feature film, and Unpei Yokoyama, who played Officer Ogawa, was recognized as the first popular movie actor. Later on, Kawai Film Production Co, Ltd. would remake the movie.
