Takashi Miyagawa, a part-time worker of no fixed abode from the Japanese region of Kansai, had told each of the women he had been dating that his birthday was on a different date.
The 39-year-old was arrested for defrauding the 35 women after pretending to be serious about relationships with them.
Miyagwa’s real birthday in November 13.
In one case, the Miyagwa told a 47-year-old lover that his birthday was on February 22, while another victim, 40, said he told her it was in July. A third woman, who is 35, said she believed it was in April.
According to SoraNews24, the total number of victims stands at 35 with the possibility of more coming forwards.
The women have all accused Miyagawa of swindling them out of £665 worth of birthday presents, clothes, and cash.
The suspect met his victims while working for a marketing company selling hydrogen water shower heads and other products.
He reportedly targeted single women and began each relationship with the suggestion that marriage would be on the cards.
However, the women ended up forming a victims’ association and reported Miyagawa to the police in February.
Investigation is ongoing.
