For many reasons the June election was unusual. To begin with, it was the first time in twenty-seven years that a general election was called due to the passage of a ‘vote of non-confidence’ in the House of Commons.Moreover, it was a ‘double election’ as the regular triennial election of the House of Councillors was scheduled for the same time. Most uniquely, it was also the first time in Japan's electoral history that an incumbent Prime Minister died in office while in the course of the campaign. Finally, it was seen as the first serious opportunity for the combined opposition forces to terminate the uninterruped one-party rule of the Liberal Democratic Party (hereafter referred to as the LDP) since 1955. Results of the election and the subsequent choice of Suzuki Zenko as the Prime Minister surprised not only observers but also the ‘insiders’ ofJapanese politics. This paper attempts to: (1) elaborate on the background that led to the election; (2) illustrate and analyze the electoral facts; and (3) examine their implications for Japan's party politics in the 1980s.
