LDP has nominated Incumbent Shunichi Yamaguchi as its candidate. Meanwhile, DPP nominated former Tokushima governor Komon Iizumi, who ran as an independent candidate for Tokushima 2nd in the last election.[7]

Masazumi Gotoda, the current governor of Tokushima who has been at odds with Iizumi, criticized DPP and Iizumi as follows.
"He (Iizumi) lost the gubernatorial election two and a half years ago, lost the last general election. And he announced that he would retire from politics, and while he was serving as governor for five terms, Tokushima's tourists and hometown tax donations were the lowest in the country. Does DPP lick Tokushima prefecture (to nominate him as a candidate)? Moreover, at the press conference, he (Iizumi) said he want to do something about Tokushima's plight. I was dumbfounded and turned upside down. He is licking Tokushima too much."[8]

In addition, Kazuto Kitajima, a member of Tokushima prefectural assembly (LDP), also announced his candidacy. Kitajima left the LDP and resigned as a member of the prefectural assembly.[9]

As a result of the election, Yamaguchi was elected by a large margin over Iizumi, Kitajima and JCP candidates. Defeated Iizumi won the seat in the PR block.[10]

LDP gain from Centrist Reform

It was the third showdown between Takumi Ihara (LDP) and Yoichi Shiraishi (CRA).

In the last election, Ihara, who was not allowed to run for PR block because Ihara was involved in a slush fund scandal, ran only in a single member district. Shiraishi won by a large margin, partly due to criticism of the slush fund scandal.

At first, former Minister of Internal Affairs and Communications Seiichiro Murakami, who was based in Imabari City, was scheduled to participate in a campaign rally to support Ihara, but was absent from Ihara's campaign rally due to protests that he was ranked 10th on the PR block's political party list.[15]

After a close match, Ihara regained a seat from Shiraishi.[16]
