TOKYO, July 3 (Reuters) - Japan's Nikkei stock average fell 1 percent on Friday after bleak U.S. jobs data revived caution about the outlook for the global economy, while retail stocks tumbled after Seven & I Holdings (3382.T: Quote, Profile, Research) reported a drop in quarterly profit.

Shares of oil and gas field developer Inpex (1605.T: Quote, Profile, Research) and other oil-related shares dropped after crude oil prices fell nearly 4 percent on Thursday.

Drugmaker Eisai Co Ltd (4523.T: Quote, Profile, Research) fell after Nikko Citigroup downgraded the stock, citing the fact that the company's Aricept Alzheimer's drug will not receive approval from the U.S. Food and Drug Administration for pediatric use and will not get a six-month extension from the patent expiry date.

Tokyo shares fell after U.S. stocks slid the previous day but trade was thin, with 942 million shares traded on the Tokyo exchange's first section compared with last week's morning average of 1 billion.
