BTS leader RM, also known as Kim Namjoon, celebrated his 31st birthday on September 12, 2025, by donating a total of 200 million won (approximately $144,000 USD) to support medical research and care. This generous act continues RM's tradition of making meaningful contributions on his birthday, and demonstrates his commitment to spreading positivity and support to those in need.

RM donated 100 million won to Seoul Asan Medical Center and another 100 million won to Korea University Medical Center. The Seoul Asan Medical Center will use the funds to help cover treatment and surgery costs for patients from economically disadvantaged backgrounds. The Korea University Medical Center plans to use the donation to improve its clinical environment and expand its range of medical services.

RM expressed his hope that the donations would provide "a small but warm hope" to patients struggling with the financial burdens of medical treatment. He stated that he wanted to participate in something meaningful for his birthday, and that it was important to him to contribute, even in a small way, to the development of medicine and the value of respect for life.

In response to RM's donation, Yoon Eul-sik, the Vice President of Medical Affairs at Korea University, expressed gratitude for RM's "warm heart" and stated that the donation would be a great help to patients regaining their health. They also pledged to "cherish the value of sharing" that RM has demonstrated and to work towards becoming a more reliable medical institution.

This is not the first time RM has made a significant donation for a worthy cause. Last year, he donated 100 million won to the Everyone's Veterans Dream project, which is part of the Ministry of Patriots and Veterans Affairs' Uniform Worker Appreciation Campaign. This donation supported national merit recipients and the families of fallen service members. In previous years, RM has also donated to the Korean Forensic Society and the Overseas Material and Cultural Heritage Foundation, demonstrating his commitment to a wide range of philanthropic efforts.

RM also celebrated his birthday by sharing a new look with his fans on Instagram, revealing blonde hair. He also shared pictures of his birthday celebrations, including a purple birthday cake. He expressed his gratitude to his fans, known as ARMY, for their support. BTS's fandom, ARMY, is known for its own philanthropic efforts around the world, further spreading a culture of sharing and giving.

RM's consistent generosity and dedication to helping others have earned him praise from fans and the public alike. His actions serve as an inspiration and highlight the positive impact that artists can have on society.
