This is a charm from Akagi Shrine in Kagurazaka, Tokyo. It features the design of Kitaro's "chanchanko" (a traditional Japanese vest) from GeGeGe no Kitaro. The animation studio is nearby, and Shigeru Mizuki, the creator of GeGeGe no Kitaro, designed it when he visited the shrine to pray for the success of the anime. Would you like one if you live far away or are unable to visit the shrine?
