The splitting problem of this occasion may be regarded as the second splitting problem to distinguish it from the one caused by a conflict between Sennosuke YOKOTA and Takejiro TOKONAMI (establishment of the Seiyu-hon Party) at the end of Taisho period which is regarded as the first splitting problem.
なお、この時の分裂問題を大正末期の横田千之助と床次竹二郎の争いによる分裂（政友本党結党）を第1次として、これと区別するために第2次分裂問題と規定する場合がある。
