A lawyer representing Yoo Byung-eon told the Chosun Ilbo on Thursday that reports that Yoo's assets total W240 billion are not true and he is only worth around W10 billion. ... Son said Yoo, a former chairman of Chonghaejin, has nonetheless "voiced his willingness to donate his entire W10 billion estate due to his deep sorrow for those who lost their lives aboard the Sewol."

While serving as a pastor in the 1970s, he established a toy company and practically forced members of the “salvation sect” to work there under poor working conditions. In a recent media interview, Chung Dong-seop, a former believer in the sect, said that Yoo preached that members would please God if they worked for the company run by the church.

“Their working conditions were miserable. They worked long hours but received a tenth of the wages of the average workers at that time. Yoo accumulated a considerable amount of money by exploiting his workers and the fortune he earned like this was used as seed money for the construction of his business empire,” said Chung,who is now a pastor.

He's known as "the millionaire with no face." And South Korean officials apparently have questions for him...
More recently, South Korean media accounts have identified him as a photographer and artist who goes by the name "Ahae."

A biography on the site describes Ahae as the chairman of 123 Farm, an organic lavender farm on the grounds of the Highland Springs Resort in California. A 2006 Los Angeles Times article names Yoo as chairman of the board of a South Korean company that owns the resort.

The biography also describes Ahae as an entrepreneur who once designed ships that traveled the Han River.
True to Yoo's nickname, Ahae doesn't show his face on the website. He only appears from behind, photographing nature scenes in his trademark style -- out an open window of his South Korean studio.

According the website bio, Ahae was born in 1941 in Japan, where his family was during Japanese colonial rule of Korea. That would make him 72 or 73. The biography describes Ahae as "an inventor, entrepreneur, philanthropist, environmental activist, martial artist, painter, sculptor, poet, and photographer."

He also has an interest in farming. In addition to the California lavender farm, Ahae supervises two organic tea plantations in South Korea, according to the bio.

"Ahae has been a conservationist all his life and has done everything within his power to ensure that his business activities do not conflict with his endeavors to maintain the purity of the natural world," the biography reads. "His focus on organic products is a natural extension of his concern for the environment, and the individual in particular."
