In 1901, however, thousands of foreigners of many nationalities travelled and resided in Japan; and thousands of Japanese were travelling and residing in many parts of the globe. Foreign vessels, flying many different flags, freely entered the harbors of Japan; and Japanese ships conducted freight and passenger services to Asia, Australasia, America, and Europe. The figures of the small amount of the foreign trade of Nagasaki in 1801 are not at hand; but the exports and imports of Japan for 1901 amounted respectively to 252,349,543 _yen_ and 255,816,645 _yen_. A Japanese of 1801 would have travelled, if he were one of the common people, by foot, and, if he were of sufficient rank or wealth, by _norimono_, or _kago_, or on horseback. The Japanese of 1901 might continue to travel by foot, and, in mountainous districts, might still use the _kago_; but they might also travel by _jinrikisha_, horse-car, stage, steam-car, steamboat, horse and carriage, electric car, and bicycle. The letter of 1801 was despatched by courier or relays of couriers; that of 1901 by mail, and communication by telegraph and telephone was becoming more and more common. There were over 3,600 miles of railway, 9,500 miles of telegraph, and, in Tōkyō alone, over 6,000 telephones. An electric railway was actually disturbing and desecrating the hallowed precincts of Kyōto, once sacred to the Emperor. And even His Majesty’s Palace in Tōkyō had been put into telephonic and telegraphic communication with the rest of the city and even of the world. Nor was travel throughout the empire itself free and unimpeded to all in 1801. The country was split up into feudal fiefs, of which each lord was intensely jealous of other lords and had to act on the defensive. Every traveller was under considerable surveillance, and had to be able to give a strict account of himself; and many “barriers” were erected where travellers were challenged by guards. The large places where the lords lived were walled towns, entered by gates carefully guarded by sentinels. In Kyōto and Yedo the palaces of the Emperor and the Shōgun were protected by moats and gateway. But in 1901 those historic castles and gateways had mostly crumbled into ruins or been destroyed in war, or demolished by the hands of coolies working under the direction of the Board of Public Works or the Bureau of Street Improvements.
