Puffy AmiYumi still hold center stage when it comes to the J-pop craze in the U.S.

Simply known as Puffy in Japan, Ami Onuki and Yumi Yoshimura have been popular ever since their debut with the single "Asia no Junshin" in 1996. And they are still drawing crowds on their current U.S. tour to promote their new album, "Splurge," released July 25.

Ten years is an extremely long run for a pop star, but Puffy AmiYumi show no signs of losing steam. They were appointed goodwill ambassadors for a "Visit Japan" tourism campaign earlier this year, and their hit animated show "Hi Hi Puffy AmiYumi" on the Cartoon Network in the United States is helping them build a young fan base.
