24th International Symposium on Spin Physics
October 18-22, 2021, Matsue, Japan

We are pleased to announce that the 24th International Symposium on Spin Physics will be held at Kunibiki Messe Convention Center in Matsue, Shimane prefecture, Japan in October 18-22, 2021. This conference was originally scheduled to be held in 2020 as "SPIN 2020" but postponed because of the worldwide COVID-19 pandemic. Although it is still difficult to predict the situation of the pandemic, we believe that we should resume this conference.

The conference will be held in a hybrid style (i.e., both of in-person (onsite) and online participations will be possible). Recently, we have successfully tested it with a domestic conference on spin physics and think this style is useful to invigorate our scientific discussions under the present situation of the pandemic.  

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 in Dubna, Russia (2012), Beijing, China (2014), Urbana Champaign, USA (2016), and Ferrara, Italy (2018). SPIN 2021 will be co-chaired by Yuji Goto and Tomohiro Uesaka (RIKEN).

The scientific program of SPIN 2021 will include topics related to spin phenomena in particle and nuclear physics as well as those in related fields.
The symposium topics cover acceleration, storage and polarimetry of
polarized beams; applications of spin physics; fundamental symmetries
and physics beyond the standard model; future facilities and
experiments; nucleon structure; polarized ion and lepton sources and
targets; spin physics in nuclear reactions and nuclei; spin physics
using photon, lepton and hadron probes; and the spin structure of
hadrons. The symposium format consists of talks in plenary and parallel sessions.

Although we will not organize a social event to minimize the possibility of the infection to COVID-19 on the site, 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 and other popular sights
Matsue can be easily accessed from two nearby local airports, Izumo
airport and Yonago airport, both of which are connected to Japan's
large international airports in Tokyo, Osaka, etc.

A preliminary webpage for SPIN 2021 can be accessed at
The page will be updated with additional information when available.
For further information or questions, please contact the organizers
directly or send an email to contact-spin2021@ml.riken.jp

We look forward to meeting you in Matsue.
