13 babies are on their way to Japan to live with their 28-year-old 'super dad' in a bizarre story which has resulted in the Thai government changing their rules around surrogacy.

Mitsutoki Shigeta's name first hit headlines in 2014 when Thai police raided a large condo and found babies and their nannies living in unfurnished rooms with a Japanese secretary. Shigeta was identified as the father who was running what seemed like a "baby factory". Nine babies were taken out of the nannies' care at the time although it turned out that he had many more.

Shigeta has recently been granted sole custody of 13 of the babies he fathered. They will be travelling to Tokyo, Japan to live with their father and 4 more of his children who were also fathered through surrogacy.

Although he is a single man, Shigeta has promised to provide them with enough carers and nurses to take care of them and plans to enroll them in an international school when they're old enough.

Although Shigeta's surrogate factory was technically legal, the discovery shocked Thai authorities who quickly put rules in place to ensure foreigners would not be allowed to use Thailand's lax rules to create their large families.

Not much is known about Mitsutoki Shigeta. His lawyer represented him at all proceedings and even the surrogate mothers rarely met him.

Through tiring investigations, journalists discovered he is the firstborn son of Yasumitsu Shigeta, a Japanese billionaire who founded a mobile phone distribution company although even this fact was hidden by the Shigeta family.

The serial surrogacy case was so puzzling that Thai police had to craft a flowchart to keep track of how he was fathering so many children at the same time. Through this, they found out that his plan to create his mega family had been carefully thought out, with his lawyers registering apartments in the children's names and spreading out deliveries between nine hospitals in Bangkok.

Even more puzzling was his motive. Shigeta told a surrogate clinic that he "wanted to win elections and could use his big family for voting." According to the clinic's founder, "He said he wanted to father 10 to 15 babies a year and that he wanted to continue the baby-making process until he's dead."yeah

His lawyer said nothing about these devious political plans, only telling the media that Shigeta "was born in a big family and wanted the children to grow up together." He also said Shigeta wanted the children to help run the family business.

Let's hope this is the ending of a exhausting journey for the babies and not the origin story of a dsyfunctional superhero family like it sounds.
