Most new technology aims to stand out. Not so with these Japanese train cars, designed by architect Kazuyo Sejima to blend seamlessly into their surroundings as they zoom from Tokyo to mountainous Chichibu, among other destinations. The key: a reflective aluminum coating meant to help them “express a gentleness and softness” rather than the usual “sharpness” of industrial machinery, per an announcement from Seibu Railway. The company plans to debut the new cars on trains in 2018, in honor of its 100th anniversary.
