Forty members of the 10th Japanese Antarctic Research Expedition left Tokyo on November 30, 1968, aboard the icebreaker FUJI, under the command of Captain Shigeo MATSUSHIMA The expedition was led by Dr Kou KUSUNOKI, also leading the wintering party of 28 men and one pressman, while the author, as deputy leader, led the summer party of 12 men and one press reporter At Fremantle, West Australia, an american scientist (aeronomy) Mr Gerard A ROACH got on board the FUJI as an observer The FUJI carried 560 tons of expedition's cargo, including a single-engine monoplane Lockheed LASA-60, and was equipped with two Sikorsky S61-A helicopters and one Bell 47G2A helicopter After anchoring at Fremantle from December 15 through 21, 1968, the FUJI proceeded to Lutzow-Holm Bay and reached the edge of fast ice on January 5, 1969, without much difficulty The anchorage was about 30 nautical miles northeast of Syowa Station, and from there the first helicopter flight was made to transport men and cargo. On the following day, January 6, the FUJI reached fast ice within 1400 meters east of Syowa Station Unloading of about 560 tons of cargo and transportation to the station were carried out mainly by two S61-A helicopters, but about 65 tons of diesel oil was transmitted by a pipeline directly from the ship to the tanks on the shore, one 50kl metal tank and three 10kl rubber pillow tanks This was the first attempt of oil transportation by a pipeline. The remaining 105 tons of heavy materials were transported by snow vehicles and sledges over sea ice. Construction works was carried out until February 20, and a new living hut (20 × 5m), an extention of garage (10 × 8m), a tidal observation hut (3 × 3m), a corridor and three rocket huts, an assembly shop (11.8 × 7.6m), a telemetry and rador station (14.9 × 6.5m), and a control center (6.0 × 3.6m) were completed For the constructions, we were provided with a new 11-ton bulldozer, a 2-ton dump truck, and a concreat mixer. The scientific activities were largely the continuation from the previous years It is, however, worthy to note that a small aircraft LASA-60 was used in aerophotogrammetry during the summer period. The aerophoto survey covered the southern part of Lutzow-Holm Bay and the Yamato Mountains about 300km south of Syowa Station. In conjunction with the study of conjugate points, the high altitude balloons were released to observe auroral X-rays during summer. On January 28 and 29, four astronomical points were newly established in the southern part of Lutzow-Holm Bay Between February 3 and 10, 15 research members studied biology, geochemistry, geology, cartography and geography in the Skallen area where they reached by helicopter. On February 15, the 9th JARE pole traverse party, after the long journey of 141 days, returned to F16 camp, 15km east of Syowa Station. At F16 the helicopter picked up 11 members, records and ice samples carried them to the ship. On February 20, the station was officially handed over to the 10th wintering party, and the FUJI took a course to the north and then to the west. On February 22, a helicopter was sent out to take the research party to the rocks of the east coast of the Riiser-Larsen Peninsula, and to bring them back. On March 3, the ship turned to the north, and left Antarctica. After staying at Cape Town from March 14 to 20 and at Colombo from April 5 to 9, the ship returned to Tokyo on April 25. The shipboard observations of upper atmosphere physics, meteorology, oceanography, and biology were successfully carried out throughout the voyage.
