From the Washington Post, October 5, 2006, p. 17:
[In] 1947, the United States charged a Japanese officer, Yukio Asano, with war crimes for carrying out another form of waterboarding on a U.S. civilian. The subject was strapped on a stretcher that was tilted so that his feet were in the air and head near the floor, and small amounts of water were poured over his face, leaving him gasping for air until he agreed to talk.
"Asano was sentenced to 15 years of hard labor," Sen. Edward M. Kennedy (D-Mass.) told his colleagues last Thursday during the debate on military commissions legislation.
If newspapers had footnotes (actually Switzerland's Neue Zürcher Zeitung does have footnotes), this might have been a footnote in the above-quoted article:
United States of America v. Hideji Nakamura, Yukio Asano, Seitara Hata, and Takeo Kita, U.S. Military Commission, Yokohama, 1-28 May, 1947. NARA Records, NND 735027 RG 153, Entry 143 Box 1025
The charge and specifications against Asano were:
Charge: That between 1 April, 1943 and 31 August, 1944, , at Fukoka Prisoner of War Branch Camp Number 3, Kyushu, Japan, the accused Yukio Asana, then a civilian serving as an interpreter with the Armed Forces of Japan, a nation then at war with the United States of America and its Allies, did violate the Laws and Customs of War.
Specification 1: That in or about July or August, 1943, the accused Yukio Asano, did willfully and unlawfully, brutally mistreat and torture Morris O. Killough, an American Prisoner of War, by beating and kicking him; by fastening him on a stretcher and pouring water up his nostrils.
Specification 2: That on or about 15 May, 1944, at Fukoka Prisoner of War Branch Camp Number 3, Kyushu, Japan, the accused Yukio Asano, did, willfully and unlawfully, brutally mistreat and torture Thomas B. Armitage, William O Cash and Munroe Dave Woodall, American Prisoners of War by beating and kicking them, by forcing water into their mouths and noses; and by pressing lighted cigarettes against their bodies.
