Though shogunal demesne and many domains purchased masu from their Masu-za to distribute in their own territories, some of the major historic domains held firmly to their ancestral masu, while others ordered their designated Masu-za, most of whom were merchants in the domain, to manufacture masu identical to kyo-masu, thus refusing the orders from the shogunate government; this custom is called 'han-masu' (masu of the domain).
天領や多くの藩では枡座から購入して自領に流通させていたが、歴史ある大藩の中には自藩伝来の枡を固守したり、京枡と同一の枡を自藩もしくは自藩指定の枡座（多くは藩内の商人）に製造させたりするなど独自の藩法に基づく枡を用いて幕府の命令を拒絶した（藩枡）。
