If she didn't have any technique, she wasn't able to sing the way she sings while being almost deaf. She had pretty low points since the beginning of her deafness, but she improved and readapted her singing many times (even readjusting her tone to be more suitable to her limitations). She's above the average of J-Pop singers (which was pretty low during her heyday, now we have some better vocalists on the scene), even she's not a remarkable technical singer.
