In 1772, the expense of dredging came from the following three sources: (1) The license tax received from Kajichi Sahaisho: 910-ryo (in silver 54 kan [unit of volume, approx. 3.75 kg] and 600 monme [unit of volume, approx. 3.75 g]), (2) Togawa Tsuijidai-gin Kashitsuke Rigin (interest from the sales of the reclaimed land of Togawa) 80-kan 596-monme and 8-bu (unit of volume, approx. 0.375 g) in silver, (3) Horie Uenibune (freighters) Funadoko-gin 64-kan and 200 monme in silver, but 2 kan out of 64 kan and 200 monme, was Funadoko-gin (boat registration fee), so the net was 62 kan and 200 monme.
