As is typical for House of Councillors elections, candidate personality and public appeal played a stronger role than they would in a House of Representatives election; the first place winner for the national district voting was Aki Fujiwara, a panelist on the Japanese version of I've Got a Secret, who broke all of the previous House of Councillors records by obtaining 1,160,000 votes.^[2]

The Japan Socialist Party (JSP) had attempted to make questions of constitutional revision the main issue for the election, whereas the LDP attempted to sideline the issue by claiming that it would not pursue any constitutional amendments unless it were to receive recommendations from the Constitutional Investigation Commission, which was still in the process of deliberating at the time of the election. Overall, the JSP lost the most in this election, losing 19 seats, whereas the LDP gained 10 seats.^[2]
