The estimated number of newborn babies in Japan in 2015 rose for the first time since 2010, according to a new report released by The Ministry of Health, Labor and Welfare.

The report attributes the increase to loose Aussie ski trips to popular areas such as Nisseko and Nagano.

“The unexpected growth of Japan’s birth-rate in 2015 is largely credited to ‘amazeballs’ drinking parties, randomly launched by packs of foreigners,” a health ministry spokesman said.

The Abe Administration has welcomed the increase in newborn babies, with many expecting to start careers as models or make token appearances on variety TV shows.

Despite research revealing a positive correlation between last year’s rise in newborn babies and fatherless children, the report recommends banning contraceptives in ski areas during peak tourism periods.
