Kirin is using its size and market power to promote its probiotic they call plasma lactic acid bacteria (Lactococcus lactis JCM5805（プラズマ乳酸菌）). This strain has immunostimulatory activity and as there is not a claim category for that, the ads have to carefully keep from making a specific claim. When you navigate over to the R&D section it gives research results, but only uses the strain name and not any product names.
Among the products containing this probiotic are a yogurt drink, a water drink, a fermented lactic acid drink and a fortified drink which also contains DHA and Vitamin C.
