The National Diet Building (国会議事堂) is where both houses of the National Diet of Japan meet.  Sessions of the House of Representatives take place in the south wing and sessions of the House of Councillors in the north wing.  Completed in 1936, it’s constructed entirely of Japanese materials, with the exception of the stained glass, door locks, and pneumatic tube system.  This postcard dates from mid-20th century and is unused.  Grade: 1
