"I am grateful he has grown this big because, honestly, I wasn't sure he could survive," the baby's mother told Reuters.

Citing the Tiniest Babies registry at the University of Iowa, Reuters reported that the previous record was held by a German boy born in 2009, who weighed 9.6 ounces, and a German girl born in 2015, who weighed just 8.8 ounces.

The Japanese baby has not been added to the registry yet.
