== Origin == thumb|left|220px|Katsuogi placed along the roof ridgepole at Ise Shrine The original purpose of the katsuogi is uncertain. A theory is that the wooden logs were initially used to weigh down the thatch roofing seen in early Japanese structures. As construction techniques improved, the need for weights disappeared, and the logs remained only for ornamental value. Their existence during the Kofun period (250–538) is in any case well documented by numerous artifacts.
