Lucky Star sent fans to the characters' home town of Kasukabe and The Melancholy of Haruhi Suzumiya notoriously caused problems for author Nagaru Tanigawa's Nishinomiya high school. However, last December's K-on! movie has some otaku saving up for airfare rather than a train ticket as they follow Ho-kago Tea Time to London.
Fan "Kamille Biden" recently posted their K-on! inspired photos of a trip to England, which Japanese anime bloggers are embracing as a "pilgrimage" to a "holy land."
