The activities in the 2006-2007 austral summer of the 48th Japanese Antarctic Research Expedition (JARE-48) are reported. JARE-48 consisted of 62 personnel including 27 summer personnel and 35 wintering personnel. In addition, several observers joined to the voyage of Icebreaker Shirase (four Japanese), operation at Dome Fuji Station (two foreigners), Japan-Germany Collaborative Airborne Survey (eleven foreigners), and terrestrial observation around Syowa Station (three foreigners). Icebreaker Shirase arrived at the ice edge on 16 December 2006. She anchored at Syowa Station on 23 December and unloaded ca. 1000 t of cargo and fuel by mid-January 2007. Because weather in this season was extremely good, transportation and construction works at Syowa Station were going well. Biological, geodetic and geological field investigations and geophysical field station observations were carried out in the Ltzow-Holm Bay region. The JARE-48 summer party and JARE-47 wintering party on board Shirase left Syowa Station on 16 February. On the return voyage, oceanographic and marine biological observations, geomagnetism and other studies were carried out. All personnel disembarked at the Port of Sydney on 21 March. A 7-person special team (five summer and two wintering personnel) for the deep ice-drilling project took air transportation from Cape Town via Novolazarevskaya Station. The team met the traverse party of JARE-47 wintering team at ARP2 point on 3 December. They carried out ice drilling to a depth of 3025.22 m at Dome Fuji Station. The summer members of the drilling team arrived in Tokyo on 20 February. One summer personnel, who conducted the Japan-Germany Collaborative Airborne Survey, arrived to Neumayer Station on 8 December. He conducted the airbone survey in the vicinity of Neumayer Station, and moved to S17 on 6 January. The airbone survey was conducted above Ltzow-Holm Bay region. He arrived to Japan on 8 February.
