Rain was born in Seoul, South Korea on June 25, 1982 as Jung Jihoon. He was extremely shy in elementary school; in interviews he's stated that he barely spoke. He caught the desire to become a dancer at a school talent show in sixth grade; when nobody from his school stepped forward to dance, he gave it a try, imitating the moves he saw on TV. The applause was extremely gratifying, and he decided right then to become a professional dancer. To learn, he sought out older street dancers who sometimes helped him--and other times bullied and beat him up. Rain and his younger sister Hana enjoyed a comfortable life until the Korean recession of 1997, when his father's mill and bakery businesses failed. Bankrupt, his father left for Brazil to pursue economic opportunities, leaving Rain's mother to try to support the family as a food vendor.

Rain got a start in the entertainment business as part of a 6-member boy band, Fanclub. Revealing abuses in the Korean entertainment industry, Rain described the Fanclub members as "caged animals" locked in the rehearsal room for up to 10 hours without food. After Fanclub released only two CDs, the company promoting them failed and Rain was back to square one. During his junior year of high school, he lived with some of his dance-group members, subsisting mostly on cups of ramen noodles. He auditioned 18 times for entertainment companies but was told that, although he was talented, he was too ugly to become a star. He was told that he should have plastic surgery to create "double eyelids", a common Korean practice to obtain more western-looking eyes. Finally, in 2000 he was accepted by JYP Entertainment as a trainee. CEO Park Jin Young, who put Rain through a grueling 3-4-hour audition, described him as "desperate" and "like a tiger who was about to starve to death" (2008 Discovery Channel documentary "Hip Korea"). JYP stipulated that Rain had to attend college, so after studying "ferociously," Rain got accepted to Kyunghee University and became a music major. He spent three years as a trainee and back-up dancer for JYP, who has stated that he was particularly critical of Rain in order to push him to be the best and keep him from getting a "swelled head."

During Rain's time as a trainee, his family lived in poverty and his mother became increasingly ill with diabetes as she lacked money for insulin or medical care. Rain drove himself hard to prove that he was ready to make his debut, but he didn't achieve success in time to save her life; she died of complications from diabetes a year before his debut. This had a huge impact on him; he has said in interviews that he regrets having had conflict with her over skipping school to go to dance practice, and that he believes she is in heaven where she can see him. He says that a major motivation in his life is to make her proud and he visits her grave before embarking on each new project. Another motivation he has mentioned is remembering what being hungry was like. He is a self-professed workaholic, and after acting alongside him in Speed Racer, John Goodman called him "the hardest working man in show business."
