Will Japan re-elect its hereditary politicians?

This article that I found on BBC, was about the problem of how most of the Japanese Politicians that are being elected are in some way related to a former politician. BBC does a good job of explaining the whole problem, but they dont offer a possible solution. They seem to discourage Japanese voters from voting for a non related politician such as Katsuhito Yokokume by expressing the idea that Katsuhito Yokume winning the election would be like an ant killing an elephant. On the other hand the New York Times suggest that Yokokume has a,"Fighting Chance," in the elections. The New York Times seems to give voters hope that if they vote for Yokokume, he will win because of his growing popularity now. To a lot of people it is a good thing if someone new, that is non-related to a former politician, is elected, but is it? Both the related and non-related candidates are expressing good ideas for the near future, so why should the election be based on if you are related to a former politician or not, instead of how the ideas offered will affect your life?
