You remember all about these bundles of one thousand origami cranes (called senbazuru / 千羽鶴), right? If not, why not go read all about them here. They are considered good luck, and a free ticket for a wish. They are common to see at both temples and shrines.
These bundles right here were at Osu Kannon (real name Kitanosan Shinpuku-ji Hosho-in, but understandably usually shortened to the much simpler Osu Kannon), one of the more important temples in Nagoya. They were hanging next to Nio, one of the historic Buddha’s protectors in Japanese tradition. Begging his favor, perhaps? You can see a larger photo of this scene at my good buddy Len’s website.
