The Rise of JYJ: Debut and Global Expansion
JYJ officially entered the scene in April 2010 with their Japanese EP, which immediately topped the Oricon daily ranking Albums Chart. This set the stage for their global ambitions. On October 12, 2010, they released their English-language global debut album, The Beginning, under Warner Music Asia. The album featured the lead track "Ayyy Girl," produced by Kanye West.
The demand for the group was unprecedented; 500,000 copies of The Beginning were pre-ordered, and the special edition saw 400,000 requests for only 99,999 available copies. To support the release, the group embarked on a worldwide showcase tour across South Korea, Southeast Asia, and the United States. This culminated in the JYJ Worldwide Concert in Seoul, a two-day event at Jamsil Olympic Stadium that drew 100,000 fans and was directed by American producer Jeri Slaughter.

Breaking Barriers in Korea and Beyond
Despite facing a ban from South Korea's three main terrestrial broadcasters, JYJ made a triumphant public return on December 31, 2010, at the KBS Drama Awards. They performed "Found You," a ballad from the drama Sungkyunkwan Scandal, which featured member Yoochun.
In September 2011, the group released their first Korean studio album, In Heaven. The album's popularity was evident from the start, with over 300,000 pre-orders on the first day and 220,000 copies sold by October, according to the Gaon Chart.
Documenting the Journey and Fan Engagement
JYJ sought to connect with fans through more than just music. At the end of 2011, they released Come On Over, a DVD documentary providing a glimpse into their private lives, including rehearsals and personal ventures. This was followed in February 2012 by The Day, a 90-minute documentary film screened in 17 major Lotte Cinema theaters in South Korea, attracting 24,000 viewers.
One of the group's most ambitious projects was the "2012 JYJ Membership Week." Held from June 28 to July 1 at SETEC in Seoul, this fan fair was fully funded by the members themselves at an estimated cost of KRW 3.7 billion. The event hosted over 15,000 Korean and 7,000 Japanese fans, featuring exhibitions and screenings, and was noted for providing significant economic benefits to South Korea.
Major Milestones and Public Service
The group's influence extended into national and international diplomacy. On February 25, 2013, JYJ performed at the 18th South Korean Presidential Inauguration Ceremony for President Park Geun-hye, performing for 70,000 people. They also served as honorary ambassadors for the 2012 Nuclear Security Summit and the 2014 Asian Games.

For the 2014 Asian Games, they produced the official song "Only One" and conducted promotional activities in Vietnam, Guangzhou, and the Philippines.

Philanthropy and Humanitarian Work
JYJ maintained a strong commitment to charity. They donated profits from their Seoul showcase to World Vision International and contributed ₩600,000,000 to World Vision Japan following the 2011 Tōhoku earthquake and tsunami. Additionally, they held charity concerts at the Tokyo Yoyogi National Competition Arena and Hitachi Kaihin Park to fund radiation monitors for schools in Fukushima and support the Ibaraki relief fund.
Legal Battles and Transition
The group's career was heavily impacted by legal disputes with their former management. In January 2013, the Tokyo District Court ruled against Avex regarding exclusive contract claims, ordering the company to pay 660 million yen in damages to C-JeS Entertainment and 1 million yen for defamation. This victory eventually allowed the group to return to the Tokyo Dome in April 2013 for "The Return of the JYJ," where all 150,000 tickets were sold out.
In recent years, the group's activity shifted. Following military service, Jaejoong and Junsu collaborated on the song "Sixth Magnitude Star" in 2022, though not credited as JYJ. By April 2023, all members had departed from C-JeS Entertainment to pursue individual careers.
