 note = {The present paper reports on the analyses of the bottom sediments distributed in part of the East China Sea. The bottom samples, 26 in total, were collected by the training ship “Kagoshima-Maru” of the Faculty of Fisheries, Kagoshima University, and of them 14 samples were employed for the project “Co-operative Study of the Kuroshio and Adjacent Regions (CSK)”, and the remaining 12 samples were used for a study of the bottom sediments in relation with trawl fishing training. The materials were taken chiefly by the Phleger gravity core sampler. Niino’s dredge and a small piston core sampler were also used. The results of the grain size analyses of these samples are as follows. 1) Along the meridian of 125°E, the maximum depth of the Okinawa Trough is 2437 meters by sounding and its position is lat. 25°-39.0’N and long. 125°-02.9’E. 2) The average gradient of 0°-01’ is measured at the depth of 200 meters at lat. 26°-36.0’N and long. 125°-02.0’E to lat. 31°-00.0’N and long. 125°-00.0’E on the continental shelf. 3) Very fine grained sand is distributed on the continental slope at a depth of 240 meters. (station 39, lat. 26°-32.0’N and long. 125°-06.0’E) 4) Fine grained sand is distributed on the continental shelf in the area southward of lat. 30°-00.0’N. 5) Muddy sediment is distributed in the area circumscribed by stations 27 (lat. 31°-18.3’N and long. 126°-51.4’E), 53(lat. 30-29.7’N and long. 125°-59.4E), and 51 (lat. 31°-00.8’N and long. 125°-02.2E) Muddy sediment is predominantly distributed at station 37 (lat. 25°-00.0’N and long. 125°-00.2E) and station 38 (lat. 25°-08.3N　and　long. 125°-02.2E), both at the south end of the Okinawa Trough.},
