Calendar of events that I know of, some of which I will attend.
Always being updated!
NOTE: Typically circuits and event spaces providers here only start taking reservations 2-3 months prior to the event date, so you will not see as many events in the schedule after 2-3 months from the current date you are viewing this. Larger organizers and some with good relationships with the venues are able to book their events for the whole year as early as January. I think it's pretty safe to say that events usually start at 9/10am and last until 4/5pm.
ATTENTION: The dates are input at Japan Timezone but some people have gotten the wrong date due to viewing the calendar in their own time zone. Please check the link I left in the details of the event to ensure you have the correct date and for further event information.
*An asterisk next to the event means I'm planning to attend that event 😉
