Takashi Miyagawa, 39, of no fixed abode was detained for defrauding 35 women, after pretending to be serious about them.
The part-time worker, from the Kansai region, in the southern area of Japan, told them all he had different birthdays in order to make sure he had a constant supply of presents.
You have to appreciate his audacity, not that we're condoning his behaviour, of course.
In one of the cases, Miyagawa told a 47-year-old lover that his birthday was on 22nd February.
But his birthday is in fact the 13 November (a Scorpio, how typical).
Another of his victim's, a 40-year-old, was told that his birthday was in July, with another being made to believe his birthday was in April.
As reported by Japanese news site, SoraNews24, the total number of women who fell victim to Miyagawa stands at 35.
But they also state that there is a possibility of more victims of the Japanese Romeo coming forward in future.
Altogether, Miyagawa has been accused of swindling the women out of 100,000 Japanese Yen (£665) worth of birthday presents, clothes and cash.
He met his victims while he was working for a marketing company, selling hydrogen water shower heads and other products.
Local news sites report that not only did he cheat the women out of money and cash, as well as some expensive tailored suits for one of his birthdays, but he also managed to sell them some of the shower devices that he was peddling, all for a profit.
It's reported that he targeted single women, beginning relationships by suggesting that he wants to get married at some point soon.
Eventually, the women teamed up and formed a victims' association, reporting Miyagawa to the police in February.
