Iwa was born in Las Piñas City, Metro Manila, Philippines. Her Japanese father left the family to go back to his native Japan when Iwa was still very young. Her family then moved to Davao due to her stepfather's job assignment there. She would later move back to Manila to pursue her studies. It was then that a friend of hers convinced her to join the third season of the popular reality show StarStruck where she passed the auditions. She was one of the favorites among the finalists, eventually finishing First Princess (first runner-up). She currently appears in several GMA and Q shows.
