There exists 1,080'harbors in Japan and as harbor facilities, the quay
ton version extension of mooring facilities is 1,162 kilometers, the breakwater
extension is 592 kilometers and the anchorage area (anchorage for large vessels)
is 1,000 million square meters.
The cargo volume handled at harbors for 1973 is as shown in Table
II - (lll) - 1 and the volume of about 2,700 million freight tons shows
a sharp increase of 22.2% in comparison to the preceding year.
Moreover, on port entering vessels, it was 9,820,000 vessels (Increase of
1.5% in comparison to that of the preceding year) and the gross tonnage of 3,039,6SO,000
tons (Increase of 17.6% in comparison to that of the preceding year) and although
practically a crablike crawl was maintained in the number of vessels, the increase
in gross tonnage is remarkable since the use of larger vessels was conspicuous.
