For those that haven’t visited Tokyo before (and maybe for some that have), the image of the city is a dense metropolitan space with high rise buildings and grand structures.  There is also a lot of smaller building with offices and housing.  However, the city is also pretty industrial.  The bay has been a center for commerce for centuries and much heavy industry grew up along the waterfront and has continued to prosper.  Haneda Airport is a short ride from Tokyo’s heart and is very convenient.  It is also surrounded by industry.  When in the terminal and looking across the airfield, you get a clear idea of the amount of industry so close to the city.  This isn’t a one off either.  Head south out of the city and you lots of similar industrial spaces.
