Answer by taking a quote from the following article:

Rain was born as Jung Ji-hoon on June 25, 1982, in Seosan, South Chungcheong Province in South Korea. His mother died in December 2000 as she struggled with diabetes. In the same year, Rain was recruited as a trainee for JYP Entertainment, led by recording artist and producer Park Jin-young. In a CNN interview and also in a Discovery Channel documentary called Discovering Hip Korea, he recalled being repeatedly rejected because of his looks: "In fact, I was told after one audition that my singing and dancing was great

On his World 2007 tour, his scheduled concerts in Shanghai, Toronto, San Francisco, and Hawaii were canceled, followed by the last concert in Los Angeles. The last event at the Staples Center was canceled only two hours prior to opening: Rain's producer blamed the situation on financial problems of the local promoter, while the local promoter blamed Wellmade STAR M calling them too "incompetent to handle the situation".  On March 19, 2009, a federal jury in Honolulu found that Rain, his former management agency JYP Entertainment, and two other promotion companies were guilty of breaching a contract and defrauding Honolulu promoter Click Entertainment for $2 million (originally just over $1 million) after the Hawaii concert was canceled and the promoters were not refunded the $500,000 licensing fee. Rain and JYP were ordered to pay $2.4 million each in punitive damages, $1 million for damages related to the fraud, and $2.3 million for breach of contract.  A separate lawsuit filed by promoters Wellmade STAR M was dismissed by a South Korean court on January 28, 2010. Judge Bae Kwang-Kuk ruled in favor of Rain and blamed the plaintiff for poor preparations surrounding the canceled U.S. tour.  In April 2010, Rain and other J. Tune Creative shareholders were accused of embezzling money from the company by a fabric manufacturing company. The company claimed they suffered financial losses. Rain and the shareholders were acquitted of the charges in December of that year. He was re investigated in September 2011 after a discrepancy was found, but was later acquitted again in June 2013.
