Saw this cool looking Shisa on the wall of an old house in Naha.
Shisa are often found in pairs at the entry way to houses and other buildings, and are also found individually on roof tops. According to the small slip of paper that came with a pair of shisa I purchased, shisa are imaginary creatures (a cross between a lion and a dog) and are believed to ward off evil, protect a house from disaster, and invite good fortune. You can read a bit more about them in a post I wrote a few years ago here.
