There is only one person in the country who has "Tokyo Station photographer" printed on a business card — Naoki Sasaki.

However, the 53-year-old is not employed by East Japan Railway Co. as a photographer. Instead, Sasaki fell in love with trains during elementary school and has now been photographing the 100-year-old terminal and the trains it services for more than 40 years.

"I wanted to do something that no one had done before. Tokyo Station is not just a terminal — it's a tourism landmark," Sasaki tells The Japan Times. "Nevertheless, there are still plenty of things people don't know about it. I could stare at the station all day and find every single detail fascinating."
