Pritzker Prize-winning architect Kazuyo Sejima has designed the Laview commuter train with huge passenger windows and a curved glass nose, which is now in operation between Tokyo and Saitama.
"This is my first time to design a train and the most obvious difference with building design is that the train can move to different places," explained Sejima.
Sejima has designed both the design concept, exterior and interior of the carriages, with sofa-like seats upholstered in a bright yellow material.

As well as designing the train, Sejima recently branched out from designing buildings by creating a multi-functional bag for Prada called The Loop.
