According to the Tweet of director Mizushima Tsutomu, he noticed that some animators of Girls und Panzer have been struggling to show pantsu of the characters although Mizushima had promised that there would be no pantsu shown in the anime. He said he will enforce the discipline of the staff to suppress the "resistance", but he would like to praise the courage if someone manages to insert pantsu scenes.

According to Ibakaki Newspaper, Girls und Panzer has already contributed a lot to the tourism of the model town Oarai. The character tickets released by the local railway have been flying off the shelves and a Japanese-style Hotel, which Matilda crashed into in episode 4, got many reservations by the fans. Ibaraki Prefecture has been publicizing the anime on the top page of the official website.
