Information about these events came to me through our
Events page on the Japan Past & Present website, which also features filters to search by event type, time period, event format (in person, hybrid, fully virtual, etc.) and more. There's also options to convert the information to your timezone or directly load it in your calendar (!).
We encourage folks to share their events (in any language!) to the page--anyone can do so--to help colleagues around the world access information on research taking place well beyond our own regions. I very much hope to see more premodern events uploaded there!
