Shinkansen bullet trains began their service in 1964, right before Tokyo hosted the Olympic and Paralympic Games that year.
Central Japan Railway says that the N700S is the first model the company has rolled out in five years. The company plans to introduce five of the trains before the games this summer and 40 by March 2023.
The N700S features a range of new security measures. Each carriage is fitted with six surveillance cameras, while the current model has two.
It can also draw power from built-in lithium-ion batteries to continue running in the event of a power outage.
