It was well-known that, in 1934, Kumakichi NAKAJIMA, the Minister of Commerce and Industry in the Sato Cabinet, stated in his article reprinted in the February issue of the monthly magazine "Gendai" (Modern times) that Takauji ASHIKAGA and the Ashikaga era (i.e., the Muromachi period) should be transvalued; and Yukimitsu, together with Takeo KIKUCHI, censured Kumakichi NAKAJIMA and forced him to resign.
また1934年（昭和9年）には、斎藤内閣の商工大臣であった中島久万吉が雑誌「現代」2月号に転載された足利尊氏と足利時代（室町時代）を再評価すべきという感想を述べたことに対して、菊池議員と共に中島大臣を攻撃し辞職させたことでも知られる。
