Kuristo Matsuri (Christ Festival)
From Yahoo! News Photo:

Japanese women dressed in kimono waltz around the 'tomb
of Jesus Christ' during a memorial service in Shingo, a village
in northern Japan, on Sunday June 5, 2005. The memorial
service, in its 42nd edition, started solemnly with a Shinto
priest praying and offering a branch of sacred trees. The
village's lore claims Jesus Christ died there and buried in the
mound-shaped tomb.

Here's an article about the strange tradition : Jesus in a snowstorm.
