Selling soy based drinks is a natural for Kikkoman, the soy sauce company. They have a full line of soy drink (or "soy milk" although dairy people complain about that term) in a wide range of flavors. Yesterday in a convenience store I spotted this item and see that Kikkoman is getting into the high value chilled cup market, going up against the mostly coffee-milk offerings. The product is called Soypresso and the only flavor was caramel. Pricing is a tad higher than PB coffee-milk chilled cups, but far cheaper than the most expensive in class - Starbucks. The label notes that the coffee is specially selected by Kikkoman. Might cater to people who actively want to buy soy, but in the chilled cup market, taste is extremely important and that has always been a challenge for soy drinks. I tried this and it was not bad, but the soy flavor was masked with coffee and caramel flavor. 豆乳 キッコーマン
