This is Shinjuku Isetan, one of the biggest department stores we have in Shinjuku. It was chosen as the most popular department store among working women last year in Tokyo. It's always crowded with shoppers, especially on the weekends!
Shinjuku Isetan was first built in 1933. Then in 1935, they bought out their neighboring department store and it was rebuilt the following year (photo below) and not much of the building has changed since then.
Right after the war, Shinjuku Isetan was actually occupied by the Supreme Commander for the Allied Powers and used as one of its bases for about 8 years, possibly because Shinjuku was located between the General Headquarters near Tokyo Station and Yokota Army Base in Fussa (which is now Yokota Air Base). It reopened as a department store after the San Francisco Peace Treaty was officially signed by Japan and the Allied Powers in 1951.
I don't go in here often, but I like to sometimes just stop and admire the building and imagine all that it has seen.
Hope you all have a wonderful Friday!
Enjoy looking at more beautiful skies all around the world here.
