I'm curious to why you looked it up in the first place
With Japan's culture, you will never fuck a 13 year old Japanese girlIt is extremely frowned upon and the girls are raised to never have sex like thatPlusYou can't fuck a 13 year old girl unless you're 16 because until you reach the age of adulthood (2O), you can't fuck someone 3 years younger/older than you are So good luck
