An ita-bag is a type of bag that is covered in badges, buttons, figurines, and other merchandise related to anime, manga, or video game fandom. The term "ita-bag" is short for "Itai-baggu," which translates to "painful bag" in Japanese. The concept originated in Japan, where dedicated anime and manga fans started decorating their bags with merchandise to show their love for their favorite characters. The most common types of ita-bags are handbags, totes, or backpacks that are excessively decorated with character merchandise. The bags usually have a see-through window built into them so that the owners collection of pins, charms, or small plushies can be seen. Ita-bags are a popular piece of apparel among female anime and manga fans in Japan. The trend first gained national attention in Japan around 2015.
