This object is known as Karakasa-Kozō and it is a part of Yōkai (妖怪, “Strange apparition”) – a class of supernatural entities and spirits in Japanese folklore. Yōkai are not literally demons in the Western sense of the word but are instead spirits and entities, whose behavior can range from malevolent or mischievous to friendly, fortuitous, or helpful to humans. Karakasa-Kozō are sometimes, but not always, considered a tsukumogami (tools that have acquired a kami or spirit) that old umbrellas turn into.
The title, like other elements in his works, is borrowed from DeMarco’s daily routine, as during the days he worked on the piece, he played a lot of board games with his family.
Much like the objects in his paintings are a representation of his everyday routine, the title is as well. It is therefore enters the composition of the painting, as can be seen at the bottom of the work.
