American fast food chains have apparently been waging an escalating (and highly competitive) war for customers in Japan, leading to the introduction of some fairly amazing (if not outrageous and/or rococo) new products for the local market, including Wendy's foie gras burger and 'lobster surf and turf' burger, McDonald's Ebi Filet-O and cheese katsu burger, and Pizza Hut's mini corn dog pizza.
You can view the 25 item slide show at Business Insider HERE.
At the end of that slide show there's also another link HERE to another slide show of 12 McDonald's products that failed in Japan. McLobster was an outrageous one that caught my eye. But mostly, they're American McDonald's standards that simply failed to catch on in Japan, apparently.
