Wine exports from France to Japan in the 12 months through July dropped 10.6 percent from a year earlier, according to wine producers' data made available by Wednesday.
The substantial fall in exports to Japan has partly caused a 2.7 percent fall in France's overall wine exports, which stood at 1.51 million kiloliters for the year.
A wine industry official attributed the slowed exports to Japan to the liquor tax hike in May and weak economic activity.
Exports to the United States decreased 8.8 percent, reflecting anti-French sentiment following the French government's opposition to the U.S.-led war in Iraq, industry officials said.
