Sō clan
In Kyoto, rumors of the invasion spread around the end of the 6th month. The raid was associated with the Mongol Invasions of Japan. Between the 7th and 8th month, Shōni Mitsusada, the overlord of the Sō clan, reported to the Ashikaga shogunate that the Shōni's deputy Sō Uemon had defeated Korean invaders. However, Korean captives were reported to have stated that forces from Ming China were planning to invade Japan. Since "shōgun" Ashikaga Yoshimochi took a harder stance toward the Ming than his father Yoshimitsu, the threat was taken seriously by the shogunate. Later, the "shōgun" received a report from the Kyūshū Deputy. Since it was considerably different from the Shōni's version, the "shōgun" felt the necessity of examining Korea's real intentions.
