改正増補 江戸大節用海内蔵 乾 / Revised Edo Dictionary, Vol. 1

Setsuyōshū is a dictionary classified by semantics. Those published between the mid-Muromachi and Showa periods were called kohon setsuyōshū, in which words were classified into forty-four divisions by the first syllables based on the iroha order (the Japanese syllabary ordering system), and further classified into semantic subdivisions like the world (universe), seasons, and plants. During Japan’s early modern period, the classification system based on iroha and the number of kana characters was devised, and illustrated dictionaries were also produced. From the latter half of the seventeenth century, maps and other information related to geography became available. A map of the “Ryukyu Kingdom” is also included in this document, which was published in the later modern period.
