The passage in the epitaph of the grave of Tsukasa SHIBA in the graveyard for Aizu clan in Kinkaikomyo-ji Temple in Kurotani in Kyoto, regrets his death as saying, together with the record of his family and the details of the incidents as above, that 'according to a tradition, it is not difficult for one to die but it is difficult to face his/her own death with a resolute attitude. It should be said that each person including Tsukasa SHIBA faced his/her own death and died with a really resolute attitude' and that 'if Tsukasa SHIBA did not die on July 15 and participated in Kinmon Coup, what an important role he would play in it! This is very regrettable.'
京都黒谷金戒光明寺の会津墓地にある柴司の墓碑銘には、上記の続柄や事件の経緯とともに「言い伝えによれば、死ぬことが難しいのではなく、立派な態度で死に臨むことが難しいという。柴司などは、本当に立派な態度で死を迎えた者だというべきだろう」、「もし柴司が6月12日に死ぬことなく、禁門の変に参戦していたなら、どれだけ活躍したであろうか。これはとても残念なことである」とその死を惜しまれている。
