What does showing the middle finger mean in Japan?

What does it mean to stick up the back side of your index and middle finger in the UK?

Content: Not only in Japan, but in most Asian countries this is a VERY bad gesture to use. Almost as bad as the middle finger is in America. If you want to beckon someone you need to use the wave gesture. Or if you want to be more Japanese, like use the “beckoning cat” gesture. It’s basically the wave gesture, but upside down. Using either one is fine. Another offensive gesture is the eyelid pull down and sticking out your tongue. This is more to mock someone rather than being rude, but it’s still not something to do in public. Slapping your butt with your butt facing the person - Basically equivalent to saying “Kiss my ass”.
