Leah Dizon received moderate success in America including the cover features of various import car magazines. Just like Eva Mendes, her modeling career in the United States gained her much attention and a fanbase overseas, predominantly in Asia.

One year after her pictures were posted up on the internet, she already had 2,000,000 hits from search engines.Following the advice of her fans, Dizon sent a demo tape with model photographs of herself to a talent agency in Japan and in April of 2006, after being accepted, she immediately moved to Tokyo. In October 2006, she released her first photobook titled Petite Amie (Girlfriend in French), which was ranked as the third best selling photobook of that year.

On February 14, 2007, she released her first CD single and DVD package, Softly under the record label Victor Entertainment(VIZL-216), which peaked at number #7 in the Oricon Weekly Chart. At the same time, she also released her second photobook titled Hello! Leah.
