A Japanese military postal stationery card from 1943, featuring the iconic red "Rising Sun" motif with bold kanji inscription 軍事郵便 ("Military Mail"). The postcard includes handwritten content in soft pencil, folded vertically and written in classic vertical style with red-lined margins. Visible postmarks are struck with circular military cancels, likely processed through a Yokohama-based depot, and dated circa Showa 18 (1943). The card was likely dispatched from an enlisted soldier during World War II, as suggested by the format and tone of the kanji script—descriptive, reflective, and respectful—common for correspondence between soldiers and family. The envelope-style flap and rear notations in Chinese characters suggest possible deployment in occupied regions or interaction with local Chinese-speaking personnel. Historically and philatelically significant, this card represents wartime communication practices and Japanese imperial postal design. Estimate "$50 – 80".
