Despite great interest in the war in East Asia, the Japanese invasions of Korea are not widely known in the West. Historian Stephen Turnbull attributes this to titles such as "Hideyoshi's Invasions of Korea" (merely an extended part of Toyotomi Hideyoshi's biography) and the "Japanese invasions of Korea" (simply a larger repeat of the Japanese wokou pirate raids) absent the distinction as a "war". Many history textbooks treat the war with only a few lines of mention, and with the exception of "Samurai Invasion: Japan's Korean War 1592–98" by Turnbull, no complete academic studies on the subject exists in English, although both Murdoch and Sansom covered the topic in some detail in their general historical surveys of Japan, "A History of Japan" (1903) and "A History of Japan" (1958), respectively. Henry Kissinger also refers to the conflict in "World Order" (2014).
