Japanese Prime Minister Fumio Kishida said Tuesday his governing party's major defeat in last weekend's by-elections was largely due to a political fundraising scandal and that he would not step down or replace party executives to take responsibility. Instead, Kishida said he will push anti-corruption measures and political reforms. “As I take the results seriously, I believe as president of the governing party we must tackle the challenges we face one by one and achieve results, and this is the way I will take responsibility," Kishida said.
