Ayumi Hamasaki
Before she joined Avex Trax, she released a single and an album both called Nothing From Nothing. But these did not become popular. Since she debuted in 1998 with "Poker Face," Hamasaki sold more than 50 records in Japan. This puts her as one of the highest ranking singers in the country. She holds many records as a female singer. These include the most number-one hits and highest sales.
