Two black and white woodblock prints featuring volvelle or wheel charts each measuring 15.3 x 20.2cm. The dial on the rice market chart is loose, there is a pin hole where a pin could be inserted to enable the dial to be used. Both prints are in very good condition.

These two rare Edo-period woodblock charts exemplify the practical ingenuity and scientific understanding of the time, offering insights into Japan's economic and maritime practices.

The rice market chart was designed to assist rice traders in swiftly determining the number of bales of rice equivalent to 10 ryō, based on fluctuating market prices. Comprising two components—a circular table and a movable sheet with a slot functioning as a dial—it allowed users to align the current rice price with the fixed amount of currency, revealing the corresponding quantity of rice without the need for complex calculations. Such tools were particularly valuable in bustling markets like the Dōjima Rice Exchange in Osaka, established in 1730. Recognized as the world's first futures trading market, the exchange facilitated the buying and selling of rice bills, reflecting the commodity's central role in Japan's economy during the Edo period.

The tide chart provided essential information for coastal communities, indicating the timings of full tides in accordance with the lunar calenda. The outer circle of the chart is divided into 30 days, representing a lunar month, while the adjacent inner circle denotes the time of day. The central section, partially shaded in brown, likely highlights specific tidal patterns or significant lunar phase. Understanding tidal movements was crucial for activities such as fishing, transportation, and agriculture. The chart reflects the Edo-period emphasis on harmonizing daily life with natural rhythms, showcasing the integration of scientific knowledge into everyday practice.

Together, these charts not only served practical purposes but also illustrate the sophisticated level of scientific and economic understanding in Edo-period Japan. They stand as testament to the era's commitment to blending empirical knowledge with daily life, facilitating commerce and navigation through accessible and innovative means.
