At Yamato Transport Co.’s delivery center in Toyota, Aichi Prefecture, COVID-19 vaccine doses are stored at below minus 60 degrees Celsius in 25 ultracold freezers, ready to be shipped to mass inoculation sites and clinics in the city.

But delivering vaccines to each site and clinic requires meticulous planning, with the company delivering doses along with syringes and other equipment to the locations based on the number of reservations made up until three days prior to the day of the inoculation.

With that in mind, Yamato Transport came up with what it calls the “bus stop” shipping system, in which it sets delivery routes and times according to the opening hours of clinics, so that it can make the deliveries to some 140 clinics and mass inoculation sites in the city at the right time.
