Human sweat-infused rice balls fashioned in the armpits of cute Japanese girls become unlikely culinary hit, at a price

It is one of Japan’s oldest snacks.

Filled with a delicious combination of vegetables and meat, the rice ball is usually shaped by hand and wrapped in a layer of seaweed.

Onigiri rice balls, Japan’s on-the-go fuel, were around even before the samurai took them onto the battlefield.

Today, this centuries-old snack has taken on a bizarre new form.

The snack is now being prepared by young women who use their armpits to shape the balls, a strange culinary twist that has gone viral on social media.

Before making the onigiri, all the ingredients and the body parts they come into contact with are disinfected.
