This is the 3rd PHENIX collaboration workshop between Japanese and Korean institutes. The first one was held in Ewha Woman's University in Seoul, South Korea (2012) and the 2nd one was held in SungKyunKwan University, Sung-Kyun-Kwan, Suwon, South Korea (2013). The last two meetings provided a good synergy effect in our contribution to PHENIX project. PHENIX soon gets into the important transition phase to renew entire detector concept through the drastic upgrade. Taking geographical advantage, it is logical to collaborate within Eastern Asian countries to maximize the outcome within limited resources. This meeting should be an opportunity to discuss how to proceed and optimize the collaboration. The program of the meeting categorized into 4 major topics 1) Introduction of forign student support program (IPA) in RIKEN, 2) presentation by IPA and junior graduate students ,3) Plan/projects of PHENIX future upgrade, 4) Research activities of collaborators outside PHENIXFrom Narita Airport, you can come to Wako-shi subway station via train and subway.
