'''Koku''' is a measurement of rice. In theory, 1 koku of rice should be enough to support 1 man for a year. When fiefs were distributed, their wealth was often assessed in the amount of rice (or equivalent goods) that the administrator could expect to receive in taxes. This, in turn, would indirectly dictate the number of men such a lord could be expected to field, if necessary.

'''Koku''' is a measurement of volume, the equivalent of about 180 liters. In theory, 1 ''koku'' of rice (about 150 kilograms) should be enough to feed 1 man for a year.<ref>It probably would not feed him very well though. Using modern Japanese figures, one ''koku'' of rice a year would mean about 1430 cal/day. The recommended diet for a moderately active male of 150 cm. is about 2000 cal/day and for a quite active male is 3000 cal/day. Though not everything can carry right over, 1 ''koku'' of rice a year was probably not really sufficient for the diet of an active warrior or peasant. (''Visual Wide Food Composition Tables'' ヴィジュアルワイド食品成分表, Tokyo Shoseki, 1996)</ref> When fiefs were distributed, their wealth was often assessed in the amount of rice (or equivalent goods) that the administrator could expect to receive in taxes, an amount known as ''[[kokudaka]]''. This, in turn, would indirectly dictate the number of men such a lord could be expected to field, if necessary.
In the [[Edo period]], samurai stipends were paid in ''koku'', and the gold currency denomination known as the ''[[currency|ryô]]'' was generally held to be roughly equivalent to one ''koku'' in value. Over the course of the period, however, the value of gold rose dramatically relative to the cost of rice,<ref>Screech, Timon. "Owning Edo-Period Paintings." in Lillehoj, Elizabeth (ed.) ''Acquisition: Art and Ownership in Edo-Period Japan''. Floating World Editions, 2007. p34.</ref> making samurai relying on stipends paid in rice less and less wealthy relative to the [[chonin|merchant class]], who earned their incomes in gold and silver.
''Daimyô'' and lower-ranking samurai alike are believed to have themselves enjoyed roughly 35% of the face-value of their stipends (or ''kokudaka'' in the case of ''daimyô''), with the rest being paid to retainers or otherwise not coming into the samurai's own personal wallet. For samurai resident in [[Edo]], stipends were paid out of a granary office in [[Asakusa]], in three installments over the course of a year. One-quarter of the annual stipend was paid in spring, one-quarter in summer, and the remaining one-half in the winter. Though stipends were nominally measured in ''koku'' of rice, samurai were often paid in a mixture of rice and gold [[currency|coinage]].<ref>Craig, Teruko (trans.). ''Musui's Story: The Autobiography of a Tokugawa Samurai''. University of Arizona Press, 1988. p.xv.</ref> Those receiving a salary in addition to, or instead of, a rice stipend, were often paid in ''[[Japanese Measurements|hyô]]'' or "bushels" of rice. One ''hyô'' was roughly 2/5 of a ''koku''.<ref>''Mining, Monies, and Culture in Early Modern Societies: East Asian and Global Perspectives'', Brill (2013), 48.</ref> It has been estimated that a woman's minimum annual expenses were on average 1.1 to 1.4 ''koku'', while a man's was around 1.8.<ref>Rebecca Corbett, ''Cultivating Femininity: Women and Tea Culture in Edo and Meiji Japan'', University of Hawaii Press (2018), 121.</ref>
The size of ships was also typically stated by its cargo capacity, measured in ''koku''. By chance, this unit works out to roughly 1/10th of the conventional unit of ship size today, namely tons of displacement. Thus, a 1500-''koku'' ship can be said to have been roughly 150 tons in modern parlance.<ref>Michelle Damian, “Archaeology through Art: Japanese Vernacular Craft in Late Edo-period Woodblock Prints” (MA thesis, East Carolina University, 2010), 105-106.</ref> That was the typical size for, for example, ''[[higaki kaisen]]'' cargo ships which carried goods between [[Osaka]] and Edo.<ref>Gallery labels, "Higaki-kaisen," [[Edo-Tokyo Museum]].</ref>
