In "Teijo Zakki" (Teijo's Notes) written by Teijo ISE, who was the expert on Yusoku-kojitsu (knowledge of court rules, ceremony, decorum and records of the past) of the Samurai class, it was documented that 'although it had been around since ancient times, since it was not to be brought out in public, the manner in which soba was eaten need not be mentioned' explaining that soba was something that the Samurai and Noble Class people ate in private.
武家の有職故実の大家だった伊勢貞丈の『貞丈雑記』には蕎麦切りを食することは「古くありし物なれ共、表向などへ出さざる物故、喰様の方式なども記さざるなるべし」と記して、武家や公家などの間では人前で蕎麦を食するものではなかったと解説されている。
