If you have ever wandered the suburbs of a Japanese city you have most likely seen, and inevitably exchanged greetings with, a Yakult Lady delivering probiotic drinks by bicycle.
Travelling by bicycle, always smiling and polite as they pass by, the Yakult Ladies have become a recognisable part of all communities in which they operate. The personal impact of delivering by bicycle brings them much closer to customers and the community than if they delivered exclusively by by car or scooter. Checking in on the well-being of the elderly as the do their rounds, offering counsel and support, the Yakult Ladies offer so many additional benefits to society.
Even if you're not a customer, you will eventually exchange a polite smile, or "konnichi-wa" when a Yakult Lady passes you on her bicycle, which is something you just don't do with the local pizza delivery guy as he darts anonymously down the road on his noisy scooter.
