Many will consider these heads to be imaginative works of art.
They may well have been inspired by a disturbing dream.....
....or by some mind-bending stimulants.
They could possibly be the work of someone fascinated by faces - as well as knockers.
That's all well and good.
However, while out walking recently in deepest rural Nagano, I happened upon a head which later caused me to have a disturbing dream, made worse by mind-bending stimulants such as red wine and cheese.
You see, from a distance it looked rather horrifying and for an awful moment I thought I'd stumbled across the following day's news headlines....
A head on a signpost - it's not what you want to see in the middle of the countryside.
