Paris Hilton is getting back to work with an overseas business trip to Asia, that had been planned months before her arrest for cocaine possession, and subsequent guilty plea to misdemeanor charges, RadarOnline.com has exclusively learned.

Hilton will be in Tokyo on Wednesday to unveil her fall/winter collection which includes handbags, watches, and her new fragrance, Tease.

A source close to the hotel heiress tells us, "Paris has taken full accountability for her actions, and went to Las Vegas ahead of her scheduled arraignment date which had been scheduled at the end of October. She is taking it all very seriously, and is focusing on her future. Paris has already contacted her doctor to set in place her counseling. She will also be setting up her community service upon her return to the United States."
