Otaku tourism involves fans of anime and manga traveling to visit locations that are significant in their favorite anime works. This type of tourism began in the 1990s and is now a core part of Japan's "Cool Japan" strategy to promote Japanese pop culture abroad. Otaku tourists, also called anime pilgrims, tend to travel individually and engage in behaviors like taking photos from the same angles as in anime works or dressing up as characters. Understanding otaku tourists from markets like China, Hong Kong, and Taiwan is important to developing the otaku tourism industry in Japan.
