The Muse­um of Aero­nau­ti­cal Sci­ence dis­plays rel­e­vant arti­facts to the avi­a­tion his­to­ry of Japan, includ­ing air­craft. Also of note is the obser­va­tion deck on the fifth floor, with views over Nari­ta Air­port. From here you can watch air­craft land­ing and depart­ing, log num­bers, and take pho­tographs.
