500px provided description: Found this tunnel while exploring the streets of Atami, a small city on the coast of the Izu peninsula, Japan. There was a hot spring inside, so a lot of steam built up halfway to the ceiling, creating some beautiful lighting contrasting the warm light bulbs inside with the much cooler color outside.

The cave's name is Hashiriyu. [#fog ,#hdr ,#contrast ,#old ,#urban ,#lights ,#colors ,#wood ,#tunnel ,#exploration ,#colorful ,#bricks ,#pipes]
