A rare original large-format poster titled “Gendai Kaisen Gainen-zu” (Modern Naval Battle Concept Chart). Issued by the Yushukai Foundation on June 15, Taisho 14 (1925). 205 × 77 cm (80 × 30 in). This highly detailed lithograph illustrates Japan’s interwar vision of a future naval battle. Combining traditional battleship tactics with new warfare elements such as airships, aircraft squadrons, and submarines. It reflects the Imperial Japanese Navy’s evolving doctrine following the Washington Naval Treaty (1922). When Japan was rethinking its maritime strategy under fleet tonnage restrictions. Above the sea, airships and observation balloons are seen monitoring the battle. Submarines advance beneath the waves, symbolizing the growing importance of underwater warfare. An accompanying explanatory sheet provides detailed notes on fleet formations, unit names, and battle stages. A vivid glimpse into the Navy’s educational and tactical thought process at the time. The Yushukai Foundation, based in the Imperial Navy’s Mizukosha facility in Tokyo. Was an officially supported patriotic and educational organization. This poster was produced for public exhibitions and naval education. To inspire citizens and cadets with a modern vision of naval power and technological progress. This 1925 edition predates the Yushukai’s better-known “Battleship Cutaway Diagram” (Taisho 15, 1926). Making it one of the earliest known Japanese visual depictions of an integrated air-sea battle. It vividly captures Japan’s transition from a purely battleship-focused strategy to a combined-arms doctrine. That would later define the Pacific War era. Original 1925 print, not a reproduction. Noticeable wear, tears, stains, and toning due to age (see photos). The main image remains highly legible and visually powerful. Very few surviving examples are known worldwide. International Buyers – Please Note. Thank you for your understanding.
