Some have claimed that the reason for the conspiracy was dissatisfaction toward Ishida Mitsunari for writing bad assessments and underreporting the achievements of the seven generals during the Imjin War.

However, Ishida Mitsunari learned of this through a report from Toyotomi Hideyori's servant Jiemon Kuwajima, after which he fled to Satake Yoshinobu's mansion with Shima Sakon and others to hide.

[4] Historian Watanabe Daimon stated that the incident was more of legal conflict between the seven generals and Ishida Mitsunari rather than conspiracy to murder him, in which case Tokugawa Ieyasu's role was not physical protection but rather mediation of complaints.

After the incident, the seven generals would go on to support Tokugawa Ieyasu during his conflict with the Western army led by Ishida Mitsunari, known later as the 1600 Battle of Sekigahara.

Muramatsu Shunkichi argued that the reason of Ishida Mitsunari's failure in his war against Tokugawa Ieyasu was due to his unpopularity among the major political figures of that time.
