In Japan, 86% of all Internet users visit retail web sites, according to a new report from web and mobile measurement firm comScore Inc. That’s far greater than the 9% of Internet users worldwide who visit retail web sites, the firm says.

While Amazon.com Inc. draws the most unique web site visits among Japanese consumers—nearly 45.4 million in May 2013—local online marketplace operator Rakuten Inc. claims the most browsing time per Japanese shopper, who on average stayed on its web site for 32.9 minutes in May, compared to 27.4 minutes on Amazon.com in the same month, comScore says. Rakuten in May drew roughly 37.6 million unique Japanese visitors.

In terms of annual web sales, Amazon is No. 1 among North American retailers, according to the 2013 Top 500 Guide; Rakuten is No. 2 in the Asia 500.
