In the middle/low latitude ionosphere, coupling processes between plasma and neutral atmosphere is important, which is a key to understand ionospheric structures of the spatial scale of 10-1000km. Under international collaboration between scientists from Japan, Taiwan and USA, we are now conducting number of observation campaigns over Japan region. WIND (Wind measurement for Ionized and Neutral atmospheric Dynamics study) is a F-region rocket experiment to study neutral-plasma coupling processes. ISAS/JAXA successfully launched the S-520-23 sounding rocket from Uchinoura Space Center on September 2, 2007. The rocket was equipped with in-situ instruments for plasma-parameters. The Li-release experiment was conducted at the rocket downleg to measure the neutral wind. A dual-band beacon (DBB) transmitter was on board of the rocket, and we received the signal at five stations including one boat under the rocket trajectory. FERIX-2 (F- and E-Region Ionosphere Coupling Study-2) is multi-radar experiment to reveal F-region and E- region coupling processes in the ionosphere. Simultaneous measurement of F-region and E-region FAIs with the MU radar and a portable VHF radar obtained much data showing the coupling through geomagnetic field line. In parallel to these observations we conducted limb imaging of the airglow in the F-region by means of ISUAL on the FORMOSAT-2 satellite in December 2006 and June 2007. Data from FORMOSAT-3/COSCMIC satellites are valuable to support these observations. In the presentation we will overview preliminary results from these observation campaigns, and discuss future collaboration for the study of middle-low latitude ionosphere.
