There are many large rail stations in Tokyo, but none have quite the elegance and history of Tokyo Central Railway Station. The station sits near the Imperial Palace grounds in the Ginza district. The classical look of the main facade is fashioned after Amsterdam's main station. In 1921, Prime Minister Hara Takashi was assassinated at the south gates. Much of the station was damaged during World War II and is constantly being renovated and improved upon.
Nowadays the station is the busiest in all of Japan in terms of train volume with over 3000 trains passing through and 381,704 passengers every day. It's the starting point of many Shinkansen trains as well as JR Trains and the Tokyo Metro. It's an excellent place to people watch- just make sure to stay out of the way of the busy commuters!
