The COVID-19 crisis has affected economy, industry, education and academia around the globe. As many scientific meetings are postponed or converted to online meetings, the 2^nd Joint Meeting of ESCHM-ISCH-ISB Japan, originally scheduled to take place in September, 2020, was postponed to July, 2021. After experiencing the great success of the 1^st Joint Meeting of ESCHM-ISCH-ISB 2018 Kraków, Poland, the local organizing committee members are preparing this Joint Meeting with great assistance of the international scientific committees of three parental societies, i.e., The European Society for Clinical Hemorheology and Microcirculation (ESCHM), The International Society for Clinical Hemorheology (ISCH) and The International Society of Biorheology (ISB). The 2^nd Joint Meeting of ESCHM-ISCH-ISB 2021 Japan was decided recently to be complete online meeting after the approval of the three parental societies.

 The three societies’ medal award ceremony and subsequent memorial lectures by awardees are not held in this online meeting. However, many alternative sessions are going to be prepared in this meeting. This meeting will be filled with plenary lectures, symposia, free communication session, electronically prepared poster (ePoster) session and industry exhibitions. Multiple ‘Rising Star Awards’ competition will be held in this meeting. Best presentation awards are prepared for both free communication and ePoster sessions. Thus, this meeting will bring you brand-new research information about biorheology, hemorheology and microcirculation! All participants will have many exciting opportunities for scientific discovery, new connections with academic experts, industry agencies, nonprofit organization and others without oversea travelling. Current scientific evidence of COVID-19 is accumulating rapidly. Therefore, it will be possible to put COVID session (symposium, panel discussion or free presentation), where we can share and deepen the cutting-edge knowledge and information about biorheologic and hemorheologic problems of COVID infection, i.e., the coagulopathy (hemostatic abnormalities) and the vascular accidents (thromboembolic event) induced by COVID-19.

 We are now creating the joint meeting program, and call for symposium is now open to visit https://docs.google.com/forms/d/1_LmByBC3bSWGqnrccq5RsXw3QLC5sSH9Paqo5qVBAOk/edit?usp=sharing. This online meeting program contains virtual tour of Fukuoka City, where key station of this joint meeting is settled and traditional Yamakasa Festival is going to be held in this joint meeting period. We continue to stand in solidarity with international organizing committees. We wish you all stay safe and healthy and appreciate participants for their continuing interest in this Joint Meeting and for their effort to prepare and submit their abstract.
