south korea has the highest rate of circumcision in east asia.  > circumcision is largely a modern-day phenomenon in south korea. while during the twentieth century, the rate of circumcision increased to around 80%, virtually no circumcision was performed prior to 1945, as it was against korea's long and strong tradition of preserving the body as a gift from parents. a 2001 study of 20-year-old south korean men found that 78% were circumcised. at the time, the authors commented that "south korea has possibly the largest absolute number of teenage or adult circumcisions anywhere in the world. because circumcision started through contact with the american military during the korean war, south korea has an unusual history of circumcision." according to a 2002 study, 86.3% of south korean males aged 1429 were circumcised. in 2012, it is the case of 75.8% of the same age group. only after 1999 has some information against circumcision become available (at the time of the 2012 study, only 3% of korean internet sites, using the most popular korean search engine naver, were against indiscriminate circumcision and 97% were for). the authors of the study speculate "that the very existence of information about the history of korean circumcision, its contrary nature relative to a longstanding tradition, its introduction by the us military, etc., has been extremely influential on the decision-making process regarding circumcision.".= isn't it strange?  for reference, a 2016 study found that rates in japan and china are only 9% and 14%, respectively.
