After the revision made effective on March 13, 1981, the route revision was performed according to alterations made to commuting districts of the neighboring high schools, by transferring the route running via Ichida and Yasuda to via Kumiyama Housing, Nagi, and Midorigahara instead.
その後1981年3月13日以降は高等学校の通学圏の変更等による改正で経路変更を行い、市田・安田経由を廃止し、久御山団地・名木・緑ヶ原経由に変更した。
