It seems Ubisoft's apology for using the Sekigahara Teppo-tai's flag without permission has not been accepted. The Japanese historical re-enactment group informed the publisher that its distinct banner had been used in concept art for the upcoming Assassin's Creed Shadows, which promptly apologised. Still, the group wants it removed from the art book, which comes bundled with the $279.99 Collector's Edition of the game.
As reported and translated by Automaton (thanks, IGN), matchlock_kage, the leader of the Teppo-tai, which holds re-enactments at Sekigahara in remembrance of one of the most pivotal battles in Japanese history, responded: "The Sekigahara Teppo-tai members discussed the matter again. We have asked Ubisoft to remove the image from the Collector's Edition art book. I'm unsure if this will be possible, but I've contacted Ubisoft through their support."
Mercilessly reloading and firing again, matchlock_kage points out that the flag, which bears the personal heraldry of military leaders who fought at the Battle of Sekigahara (1600), is anachronistic in Shadows' setting, which takes place in 1579. We'll be interested to see if the Teppo-tai successfully gets Ubisoft to remove the flag from the art book in question, and we will keep an eye on the situation as it develops.
