User Meeting 2023


The 13th MECHANICAL FINDER User Meeting 2023 aims to provide on-site participation and presentations with sufficient infection control taken care of. We are planning to hold the meeting in a hybrid following the previous one, but we would be happy if you could join us on site.
Regarding language, in principle, on-site and online language of this User Meeting will be Japanese. Presentations by overseas will be available to on-site and online participants as English video presentations. For overseas participants, some presentations will be available in English on-demand after the meeting. Presentations marked withare available on Youtube.
