The subway underground world exist within perfect darkness, oblivious to the light and sense of vision of the world above the ground. To discover this world was a truly magical experience, Naoya Hatakeyama
Underground series from the Japanese photographer Naoya Hatakeyama is a collection of photographs taken in the vast underground spaces under the mega cities like Tokyo, Osaka or Paris. Japanese photographers Hideaki Uchiyama and Joe Nishizawa have also made some remarkable photo-works in the underground space, but Naoya Hatakeyama’s images are not focused on hi-tech constructions, he is rather capturing the fascinating light conditions when desolate dark tunnels are exposed under strategically placed spotlights.
The photo book Naoya Hatakeyama: Underground is published in March 2000:

it is what it is 
great work (particularly the last one) I’d love access to places like these…I much prefer the texture and mood of these works to the other photographers mentioned, much closer to how I imagine such places would be, i.e. dark and mysterious.
yes, I totally agree:)
