Kyōto is the stronghold of the Japanese Communist Party and the 1st district was among the few in the country where the party ever nominated more than one candidate – successfully so in the 1972 and 1979 elections; but in 1990, it lost both candidates due to vote splitting. Facing dwindling support for the major parties in the 1970s, the LDP often nominated only two candidates, the JSP just one candidate in Kyoto 1st district.
Asterisk - The Amami Islands district was added when the islands were returned to Japanese sovereignty in 1953; in 1992, they were absorbed into Kagoshima 1st district.
