Postal workers erected this monument at the Zenkoji Temple in Nagano, Japan. It stands in memorial to the spirits of lost and undelivered letters. According to the sign, "there are approximately 1.8 million pieces of undeliverable mail in Japan annually." I love everything about it. The concept that letters have spirits is endearing to me. It was an integral plot point to one of our L.W.A. book club picks; Going Postal, by Terry Pratchett. Whenever I finally make it to Japan, I'd love to visit here and pay my respect to the spirit of the mail.
