Japan is absolutely horrible to its women. Women are expected to take care of their family, their own elderly relatives and their husband's elderly relatives. It's one of the many reasons why so many Japanese women are refusing to marry and have families.
Maybe the US doesn't have it right, but, with respect to its women, Japan has it very wrong.
The biggest problem with the US is that you need a car to do anything. This includes things from basic groceries to the doctor. That's terribly limiting to the elderly.
