Ichiko lives the life of a hikikomori (shut-in) at her parents' home. However, when her sister gets a divorce and moves back home, Ichiko decides to move out and live on her own because they don't get along. The only minor happiness in Ichiko's dreary life is working at the 100-yen store where she can catch glimpses of an aging boxer named Yuuji practicing at a nearby gym. One day, the two move in together after getting to know each other better and Ichiko's life begins to change drastically as she takes up boxing herself.
100 Yen Love tells the emotional story of someone who discovers a passion that has the potential to change her life. She goes from someone you want to throw out of your house to a woman you root for completely. You'll cross your fingers and pray for her to make it all the way because that one single win would mean everything. Towards the ends, I was actually almost tearing up, and it's been a long time since a movie did that to me.
