I believe that しかたがない is a very important value that everyone should embrace. People in our world are so caught up in changing things so it fits what they want to be or what they want to happen. This is simply impossible. You cannot change everything to fit your views and there are somethings that just cannot be helped. If something were to happen, such as the death of a family member or a natural disaster or even just a broken arm, you can’t change that. You just have to accept that it’s something that has happened.
However, in Sumiko’s case, しかたがない is something she should not embrace. She should stand up and not let anyone tear her down. She needs to let the world know that what is happening is wrong. The older generation, they embraced しかたがない too much. They accepted what happened to them without asking if it was right or wrong. They didn’t stand up because they believed that it couldn’t be helped.
So yes, at its core, しかたがない is an amazing value that should be embraced by everyone no matter what culture. Our society is too stressed trying to change things that can’t be changed. But in situations of injustice, しかたがない should be discarded because things can be done to help. Things can change. You just have to be willing to stand up.
