油すまし Very little is known about the lifestyle and habits of this reclusive yokai. The most well-known abura sumashi lives in the Kusazumigoe Pass in Kumamoto, but only ever appears briefly to travelers. Occasionally, an old grandmother walking the pass with her grandchildren will say, “You know, a long time ago, an abura sumashi used to live in these parts.” And occasionally a mysterious voice will call out in reply, “I still do!” Sometimes the abura sumashi even appears to the travelers, materializing out of thin air.
