We are pleased to announce that the registration for the 24th International Spin Symposium(SPIN2021) is now open at the symposium webpage: https://spin2021.riken.jp
The symposium will be held at Kunibiki Messe Convention Center in Matsue, Shimane
prefecture, Japan in October 18-22, 2021, in a hybrid style, i.e., both of in-person (onsite)
and remote (online) participation will be possible. Based on the current status of COVID-19,we don’t know how much in-person participation will be possible, and we cannot respond tovisas or invitation letters at this time. We hope that the situation will improve so that as manypeople as possible can participate in-person.
This conference series has been held jointly since 2000, combining the High Energy Spin
Symposia and the Nuclear Polarization Conferences. The most recent symposia took place inDubna, Russia (2012), Beijing, China (2014), Urbana Champaign, USA (2016), and Ferrara,Italy (2018). The scientific program of SPIN2021 will include topics related to spin
phenomena in particle and nuclear physics as well as those in related fields. The symposium
format consists of talks in plenary and parallel sessions. We will have poster sessions as well.
Although we will not organize a social event to minimize the possibility of COVID-19
infection, we would like to introduce Matsue city and Shimane prefecture as a very attractive

place in Japan. This place is a famous and interesting area with over 2,000 years of history
ranging from the Japanese creation myth era to modern times. You can find the Izumo Taisha(Grand Shrine), the historic Tatara Iron Mill, Matsue Castle, famous Japanese gardens andother popular sights.
Please send your abstract by August 15, 2021, and the deadline for the registration is on
September 30, 2021. We will collect registration fees to cover the costs of publishing thesymposium proceedings and holding the symposium in a hybrid style. Please see theregistration section below. There will be no registration fee for non-presenting audience
participants, but we would appreciate your contribution of many presentations. If you have aquestion, please do not hesitate to ask us. We look forward to meeting you in Matsue, albeit
in a hybrid style.
