One of Japan's top-notch architects is building an invisible train, just like her other works that totally blend in with the surroundings. Kazuyo Sejima is known for creating buildings that become one with the scenery. The architect's work has been described as "fluid, transparent and intertwined with nature", one that has also earned her the prestigious Pritzker Prize.

Her innovative style can be seen in northern France at the Le Louvre Lens Museum:

Sejima, along with her firm SANAA, has now been asked by the Seibu Group - a holdings company known for its trains and hotels in Japan - to work on existing trains and give them a complete a new makeover.

The trains will feature a "reflective" surface that will make them "disappear" into the environment. The trains will connect Tokyo to other parts of Japan.
