Known as Sue, she rose to fame as a member of the Japanese pop duo PUFFY with Ami Onuki.
She had a fairly successful acting career, appearing in such films as Mohou-han in 2002, Inu to arukeba: Chirori to Tamura in 2004, and The Neighbor No. 13 in 2005.
She played herself in the live-action segments of PUFFY's show, Hi Hi Puffy AmiYumi, but she was voiced by Grey DeLisle for the animated portions.
She auditioned for a Tokyo talent search and was chosen for PUFFY as a result; she and bandmate Onuki would host the talk show Pa-Pa-Pa-Pa-Puffy from 1999 until 2002.
She married Takanori Nishikawa in 1999; he divorced her in 2003 after she was accused in the media of an extramarital dalliance. She remarried in 2009 and had a boy in 2012.
