Body parts in four separate bags were found in Khlong Pra Ong Chao Chaiyanuchit in Bang Phli district of Samut Prakan province east of Bangkok, police said.
The canal search was conducted after the Bangkok Metropolitan Police Bureau interrogated Pornchanok Chaiyapa on Tuesday.
She allegedly confessed she killed Yoshinori Tetsuo for his money, cut his dead body into pieces and dropped them into the canal, according to acting deputy national police chief Pol Lt Gen Ruangsak Jarit-ek.

The officer claimed Ms Pornchanoki's husband, Somchai Kaewbangyang, admitted he was involved in the killing of the 79-year-old man.
The couple were arrested in Ang Thong province on Monday. They were sent by police to a military camp in an unknown location for detention and interrogation.
Ms Pornchanok had reportedly been with Mr Tetsuo before his disappearance. Her husband is a taxi driver.
Forensic experts were called to the scene at the canal late Tuesday night to begin a formal investigation of whether the body parts match the missing man.
