Michael Howard (citing Hahlweg's introduction to the 16th German edition, 52) noted in his introductory essay to On War ("The Influence of On War"), 37-38, that Vom Kriege's publisher, Dummlers Verlag, sent an advanced copy of the fifth edition to Japanese General Count Jamemoto Kuroki (18441923) in 1904. Kuroki, victor over Russia in the battle of the Yalu, responded that Clausewitz's work had already been translated into Japanese and had been a significant influence on Japan's conduct of the war. Just which work of Clausewitz-and which translation-Kuroki was referring to is problematical. Some Japanese officers being trained in Germany became familiar with Clausewitz c.1887. At some point, a Japanese translation of the Principles of War was made, evidently based on a French translation: Taisen gakuri, published by the Gunji Kyoiku Kai (Association for Military Education) in 1903 if not before.
On War itself was translated by Mori Ogai (a medical oficer in the Imperial Army better known as a novelist and poet), as Senso ron beginning in 1899. Mori had earlier (1888) translated portions of the book orally at the request of Japanese officers in Germany. Mori produced copies, but it does not appear to have been officially published as a book; parts of it appeared as a serial in a local newspaper, Moji Shinpo, in February-May, 1904. Shimada Kinji, Amerika Ni Okeru Akiyama Saneyuk (Tokyo: Asahi Shinbunsha, 1975), 252-253.) It appears in Mori's collected works.
There appear to be at least two other Japanese translations of On War: Karl von Clausewitz, trans. Shinoda Hideo, Senso ron (Tokyo: Iwanami Shoten, date uncertain), 3 vols. [Encyclopedia Japonica (Tokyo: Shogakugan, 1968), v.6, p273]; trans. Tantoku Saburo, Senso ron, Genda in No Tame No Koten Sirizu 10 (Tokyo: Tokuma Shoten, 1965).
There are a number of major commentaries: Hasegawa Keitaro, "Senso ron" o yomu: Ima naze Krausewittu ka, kaku no jidai no senso to seiji no tetsugaku ("Essay on `On War' with practical application to today's society," evidently a businessman's guide), Nijuisseiki Toshokan (Tokyo: PHP Kenkyujo, 1983); Ohashi Takeo, "Senso ron" Kaisetsu: "Senso ron" to Senshi (Commentary on On War) (Tokyo: Nihon Kogyo Shinbunsha, 1983). (Translations courtesy Sumiko Otsubo of OSU, 1990.)
There is also a reference in a German bibliography to three works in Japanese, but the information is sketchy and it is not clear whether they are articles (as seems most likely) or books. Translated into English, the three works are:
1. Goda, Yutaka. The Life of Carl von Clausewitz. Tokyo, 1982.
2. Ido, Mitsuaki. The Foreword of the Work, On War. Tokyo, 1982.
3. Ohhashi, Takeo. Explanations of the Foreword to On War. Tokyo, 1982.
