A made-up term used by Charlie Sheen in the Two and a Half Men episode entitled "Ow, Ow, Don't Stop" aired on 11/22/2010. There is much speculation that it might be a crude sexual term like many of the invented sex acts seen here on Urban Dictionary. Many fans have created their own obscene definitions on sites such as Yahoo Answers.

Some have theorized that Japanese Rain Goggles may be in reference to Mejikara anti-wrinkle goggles, which are made of silicone rubber. Charlie may have meant Courtney's fake boobs, also made of silicone, were in his eyes.
Charlie: "Have you ever had a woman give you Japanese Rain Goggles?"
Allan: "I've never even heard of that."
Charlie: "Neither had I until last night and now I don't know how I ever lived without 'em!"

Girl: "What are Japanese Rain Goggles?"
Boy: "I'll show you later baby."

Fictitious sexual act performed on the TV show Two and A Half Men. In the episode, Charlie Sheen's character refers to his new girlfriend, Jenny McCarthy, giving him Japanese Rain Goggles. In the context you are to assume this is like a Dirty Sanchez, Dutch Oven, or similar act.
She was unbelievable in bed. She just gave me a set of Japanese Rain Goggles, like I've never had before.
