In the past, Ryu Matsumoto of DP was unrivaled, but he lost to Takahiro Inoue of LDP in 2012 Japanese general election due to a slip of the tongue while serving as Minister of Reconstruction.[1]
Meanwhile, Yūji Shinkai, a LDP member like Inoue, was seeking to run in the district.
Therefore, LDP decided to nominate Inoue and Shinkai as independent candidates and nominate the winning candidate. As a result of the election, Inoue won,[2][3] and then Inoue has continued to win in a stable election campaign.
