JR Tokyo Station Marunouchi Bldg
The Marunouchi Building of JR Tokyo Station (JR東京駅 丸の内駅舎) was constructed in 1914 as the station building of Tokyo Station of the then state-run railway.
It's a massive brick edifice designed by Tatsuno Kingo, one of the first Japanese architects who mastered Western architectural design, and is designated as an Important Cultural Property. It is facing westward against the Imperial Palace, and its central gate used to be solely for the Imperial family's use.
The rooftop domes of the construction were heavily damaged by the air raids of WWII and were replaced with more simple roofs after the war, but recently they got restored in the original way.
