Japan

America has the ALS Ice Bucket Challenge. Japan has, well, this.

According to the Herald Sun, 

A group of Japanese porn actresses are preparing to have their breasts squeezed by fans for 24 hours this weekend for a charity event loosely translated as "Boob Aid".

The nine adult movie stars told local media on Monday they could barely contain their excitement about the "Stop! AIDS" campaign event — which will be televised live — but asked, perhaps somewhat optimistically: please be gentle.

Apparently this has been going on since 2003. And SHOCKER - it's successful.

From Uproxx (with pictures!): 

For a minimum donation of 1,000 Yen (about $10) visitors to the company's Shinjuku studio in Tokyo met face-to-face with and got to grab the exposed chests of five anchors of the channel's naked news programme. The event - the eighth annual '24-Hour TV: Eroticism Saves the Earth Telefon' - began on Saturday morning and raises around two million Yen (just shy of $20k) every year by offering direct interaction between its leading ladies and he public.

As long as it raises money for a good cause, I guess I'm in favor?
