Koreans Illegally Entering Japan

A Korean name changing law is allowing Koreans to illegally enter Japan:

A 44-year-old South Korean woman who was deported last spring for illegally entering the country was found to have reentered Japan twice in a year by changing her name, although the Immigration Control and Refugee Recognition Law does not permit deportees to reenter Japan for five years, The Yomiuri Shimbun has learned.

The woman was issued a passport under the new name and came to Japan in August 2006, three months after she was deported, and again in January.

Because of a South Korean Supreme Court decision in November 2005 facilitating name changes, similar illegal entries into Japan by South Koreans reportedly have been increasing. Immigration authorities have strengthened their measures to halt illegal entries in the country through such ruses.

The Osaka Regional Immigration Bureau and the Osaka prefectural police said the woman, Choe Mi Gyon, was arrested in April last year, when she was working as a hostess in a bar in Kita Ward, Osaka, on suspicion of violating the immigration law as she had no passport. She was subsequently deported.

I bring this up because if Korea gets a visa waiver from the United States could Koreans deported from the US do the same thing to reenter the US?  It seems like an issue that could impact any visa waiver agreement between the US and Korea.  It seems it would be wise for the South Korean government to amend this law before it does become a visa waiver issue.
