About five hundred people from Yunho’s Japanese fan page “Let’s Go Together” participated in raising money and on July 29, 2011 donated 500,000 yen (approximately $6,400 USD) to Japan’s earthquake relief. Special towels were created on the fan page, “Let’s Go Together” and these towel packs were sold to each member of the on-line community to raise donation money. This was the third time they have donated money, accumulating to a total of 1.5 million yen (about $19,200 USD).

Members of Yunho’s Japanese fan blog ‘ONE‘ donated nearly $20,000 to a social welfare association in his hometown of Gwangju, celebrating his 27th birthday. His fans in China also volunteered their time with the less fortunate, and donated enough money to support a young girl living in a difficult situation in China so that she can live comfortably for an entire year.
