Japan Prime Minister Shinzo Abe announced on Monday a departure tax for all anime leaving the country, the first new tax in 27 years.

The tax will be added to all anime purchases made from overseas.

The government announced additional charges for anime containing any female characters that wear mini-skirts or look younger than 18.

“These extra costs will apply to around 90% of all anime sales,” says NHK journalist Ero Isuki.

The government expects the new tax to generate about 10 trillion yen in revenue in fiscal 2019.

The funds will be used to research possible techniques to engineer higher pitched female voices.
