Design

The trains are designed by Kazuyo Sejima, and feature large windows and a rounded front end with an oval windscreen.[3][1]

Based on the concept of "a new train that no one has ever seen before," it was designed based on the following design concepts.

  • A limited express that blends softly into the landscape in the city and nature
  • A limited express like a living room where everyone can relax
  • A limited express that creates new value and becomes a destination, not just a means of transportation
  • Rounded front
