2026 Nissui Fish Calendar, brand new and unused. Size: Approximately 45cm (height) x 53cm (width) This calendar uses "Gyofu" (fish charts), created by the Biology Department of the "Hayatomo Fisheries Research Association" (later the "Hayatomo Fisheries Research Institute" and "Nissan Fisheries Research Institute"), the first private fisheries research institution established during the founding and expansion of Nissui in the early Showa era. These charts were produced as part of their research on fishing grounds and fish species. Gyofu are detailed illustrations of fish, created over approximately 20 years by Toshio Kumada, the head of the research, and others. The artists observed and sketched on board trawlers, capturing the true appearance of the fish. These meticulous and delicate original color drawings, numbering over a thousand, have been preserved to this day. If anyone is interested, please consider purchasing.
