"Sengakuji", the 8th play of Mayama Seika's cycle "Genroku Chûshingura", originally entitled "Sengakuji no Ichinichi", was premiered in November 1941 at the Tôkyô Gekijô [casting].

"Sengakuji" is made up of 1 act (4 scenes).

At the opening of the act, all the Akô rônin present Kira Yoshihisa's head at the grave of Asano Naganori. The members of the Akô vendetta expect to commit seppuku in the precincts of the Sengaku Temple, and any noise startles them, fearing an attack by the enemy forces. They are terrified of being killed in battle before they can die honorably. The leader of the vendetta, Ôishi Kuranosuke invites all the rônin to burn incense at their lord's grave, surprising young Hazama Jûjirô by calling on him first, as he was the one to find Kira Yoshihisa. He then calls Takebayashi Tadashichi, and the two regret their earlier argument over who came first. Kuranosuke reminds them that the vendetta was a collective effort, with no distinction of who took the lead. The temple priests invite them to eat and rest, but Ôishi Chikara, just fifteen, and Yatô Emoshichi, seventeen, the youngest members of the vendetta, are eager for everyone to commit seppuku.

Although they had all agreed to follow this path, up to now, their sole duty was the killing of their evil enemy. Kuranosuke is uncertain if dying here is the best way to honor their loyalty to their lord. He has sent representatives to surrender to the Shogunate, as their actions have not only violated the law but also challenged the judgment passed on their lord. As they enter the Sengaku Temple, a man named Takada Gunbê appears. He had once been a strong partisan of the vendetta, but when the time has finally come, his uncle forced him to break his vows and leave the plotters, threatening to expose their plan to the shogunate. Now, Takada is thrilled by the success of the vendetta and highly desires to rejoin the rônin, but they all turn him away, branding him a traitor. Takada argues that Horibe Yasubê, of all people, should understand that he was no traitor and had no choice. Horibe does understand, but replies that this is the role fate has assigned him. Heartbroken, Horibe too rejects him, declaring that their friendship is now over.
