To give the picture some context you might be able to think of John Wayne. The US has cowboy stories and to keep with stereotypes, Japan has samurai stories. Not 100% sure if this guy was a samurai or not, but today this traditional figure still makes his way into modern Japan by way of comics and RICE fields. Not all rice in Japan is grown like this but from time to time a farmer will take a risk and decide that the patties need a little flavor. Using different strains of rice the stalks grow with different colors and with careful planting methods any figure can grow into being.
