【Nov 29-Dec 2, 2022】International Symposium ‘KASHIWA DARK MATTER SYMPOSIUM 2022’ to be Held in Hybrid Style


We are happy to inform you that the call for registration and abstract submission for this year’s Kashiwa Dark Matter Symposium 2022 has now been opened. The Kashiwa Dark Matter Symposium 2022 hosted by ICRR will take place in hybrid style (on-site and online) from Tuesday, November 29 to Friday, December 2, 2022.

We would like to share three news:
1. Registration and abstract submission page and deadlines.
2. The time schedule and on-site venue (see below).
3. Confirmed invited speakers (see below).


To join the Kashiwa Dark Matter Symposium 2022, please register at

The registration deadline is Nov. 4, 2022, 23:59 UTC.

For on-site participation, a registration fee of 2000 Japanese Yen is charged (in cash at check in). Please note that due to preventing the spread of COVID-19, on-site participation is limited to 60 persons on a first-come-first-serve basis. For online participation, there is neither a registration fee nor a limitation of participants. We encourage especially young postdocs and students to participate and to present their work at the symposium. Abstracts for oral and poster presentations can be submitted via https://2022.kashiwa-darkmatter-symposia.org/registration.html.

The abstract submission deadline is Oct. 14, 2021, 23:59 UTC

Oral presentations can be given in person or online. Posters will only be presented online, and include a max. 2-minute pre-recorded flash-talk. Oral presentations are 10 minutes with 3 minutes Q&A.

Please note that you can register earlier and add an abstract submission later at any time until the abstract submission deadline.

We are happy to announce the fourth Kashiwa Dark Matter symposium at the Institute for Cosmic Ray Research of the University of Tokyo. For the first time since 2019, the symposium will take place again in-person at the University of Tokyo Kashiwa Library Media Hall. The symposium will be held fully hybrid, allowing a worldwide inclusive and eco-friendly participation in an ongoing pandemic.

The Kashiwa Dark Matter symposium series brings regularly together international researchers from all relevant experimental and theoretical fields in current and future dark matter searches. This year, the symposium will include a focused session on searches for light Dark Matter from the keV scale down to μeV and beyond, including theoretical aspects and recent developments of detector technologies.


– Dark matter theory
– Collider experiments for dark matter searches
– Dark matter direct detection experiments
– Dark matter indirect detection experiments
– Astrophysical and cosmological constraints on dark matter
– Searches for light Dark Matter from the keV scale down to μeV and beyond

We are looking forward the fourth edition of the Kashiwa Dark Matter Symposia. Also, please forward this information to any interested colleagues.
