字母“CPO”代表中央采购办公室。该标记表明该花瓶在第二次世界大战结束后不久在被占领的日本的美国军事基地被出售。战争结束后，金属和其他原材料的供应受到限制。制造商向CPO申请获得他们生产的产品所需的材料，这些产品要么在基地出售，要么出口。花瓶上的标记大约从1946年到1948年使用。这个花瓶有汉字，所以它无疑是在中国生产的，在战争期间带到了日本。
The letters "CPO" stand for Central Purchasing Office. The mark indicates the vase was sold at a U.S. military base in Occupied Japan shortly after World War II ended. Immediately after the war, supplies of metal and other raw materials were limited. Manufacturers applied to the CPO to get the materials they needed to make goods that were either sold at the base or exported. The mark on your vase was used from about 1946 until 1948. The vase has Chinese characters so undoubtedly it was made in China and brought to Japan during the war.
