These methods were novel to the kimono fabric business, for in those days, it was customary that payment was done on credit until a later day, and the unit of trade was in 1 tan (length app 10.6 m and width apploximately 34 cm); and this new system was useful for the customers, too, for while demanded to pay in cash, merchandise in good quality might be bought in the amount necessary for a good price (since there was no danger of welshing the credit, there was no need to tack on for that risk).
当時、代金は後日の掛け（ツケ）払い、売買単位は1反単位が当たり前であった呉服業界においては斬新であり、顧客に現金支払いを要求する一方で良質な商品を必要な分だけ安価で販売した（ツケの踏み倒しの危険性がないためにそのリスク分を価格に上乗せする必要性がなかった）ために、顧客にとっても便利な仕組みであったのである。
