"Genpei Seisui ki" (Rise and Fall of the Minamoto and the Taira clans) describes the following story: Yoshinaka remained unwilling to part from Ishi in Gojo Dairi (the Emperor's residential compound) in the middle of being attacked by MINAMOTO no Yoshitsune, so Kazukage Echigo no chuta (referred to Iemitsu in "Heike Monogatari" - The tale of the Heike) and Saburo TSUNADA who lived in Kaga Province committed Seppuku (suicide by disembowelment) to remonstrate that behavior.
『源平盛衰記』には、源義経に攻められている最中、義仲が五条内裏で伊子といつまでも別れを惜しんでいたので、越後中太能景（『平家物語』には家光とある）と加賀国住人の津波田三郎が切腹してこれを諌めたとする逸話が記されている。
