Japan’s NTV is currently running its 29th “24 Hour Television” special, which consists of having several celebrities stay up 24 hours straight so they can act as announcers and commentators for the typical variety shows that NTV would air. In this clip, gravure idol Yuka Kosaka is chosen for the challenge of changing into a bikini on stage and spending 30 seconds in a vat of extremely hot water:

If you don’t understand Japanese and didn’t notice what’s special about this clip, I’ll give you a hint: look at her clothing as it falls to the ground while she changes into the bikini…

Yep, that’s right, she’s on her period! Another embarassing moment brought to you by 24 hour television..
