given the way osada skated in the 1982–1983 season, many expected her to continue to progress in the world ranks. however, she placed poorly in compulsories at 1983–1984 all japan championships, where she finished 4th, costing her the opportunity to compete at the sarajevo olympics in 1984. around this time, osada experienced a growth spurt, which made her triple jumps less consistent and less dynamic. although she won a couple of bronze medals at nhk trophy, she was never able to regain her national title, nor was she able to make the japanese world or olympics team. by 1986, she was no longer training seriously, as she shifted her focus to her studies at hosei university. she retired quietly after the 1989 season.
