Unlike the Tokyo city constituency, the Seiyūkai's position in the still mostly rural Tokyo counties district was strong and it managed to win four of the five seats several times even though anti-mainstream candidate Takagi Masatoshi achieved to be elected with the highest vote (top tōsen) four times in a row. Takagi, a blind Shinagawa native, had been a member of the prefectural parliament from 1881 and had already been elected to the first Diet in 1890 where he opposed the Meiji government's military expenditures[1] – as did initially most representatives from the former Freedom and People's Rights Movement before the Seiyūkai was formed. Another representative for the counties district, first elected in 1917, was Maeda Yonezō who went on to become co-president of the Seiyūkai in the 1930s alongside Hatoyama Ichirō, Shimada Toshio and Nakajima Chikuhei.
With the return to "small" single- and two-member districts in the 1920 general election, Tokyo's counties and Hachiōji that was elevated from town to city in 1917 were divided into five electoral districts.
