Of about the 3,500 Allied POWs who had died in Japan during the war, the ashes of the Americans and Netherlanders were brought back to their respective homelands. As to those of the people of the Commonwealth - Australia, Canada, Great Britain, India, and New Zealand - theirs were buried in the Commonwealth war Cemetery in Yokohama.

The site of this war cemetery was a park for the children in Yokohama-city before the war, but it was requisitioned by the Occupation Forces after the war, and at the time of signing of the Peace Treaty in 1951, it was decided that the site would be used as the war cemetery of the Commonwealth. Although the Japanese Government owns the land itself, it was permanently loaned out without compensation to the Commonwealth War Graves Commission headquartered in Great Britain, and the said Commission has been responsible for the maintenance of this war cemetery.

A vast 13-hectre of the cemetery is divided into the British section, Australian section, Canadian & New Zealander section, Indian section, and Postwar section. On each gravestone inscribed are the name of the deceased and his unit, rank, serial number, age, and date of death. In addition, the Cremation Memorial at a corner of the British section, the ashes of the 335 POWs, including 48 Americans and 21 Netherlanders who died shortly after arriving from the Southeast Asia at Moji are enshrined. Of the approximately 2,000 people sleep in this war cemetery, 1,700 died during the World War Ⅱ as POWs. Others died during the occupation or killed in action during the Korean Conflict.

At the cemetery, on April 25 (ANZAC Day), a memorial service is held under the auspices of the Australian and New Zealand Embassies. On the first Saturday of August, a commemorate service by the Japanese civilians with Mr. NAGASE Takashi, Prof. AMEMIYA Tsuyoshi and Prof. SAITO Kazuaki as leaders, and on Sunday shortly before or after November 11 (the Remembrance Day), a memorial service by the Ambassadors of the Commonwealth, respectively each year.
