I'm reporting this after the fact, but I appeared at "Fin/Sum | BG2C 2020," co-hosted by the Financial Services Agency and the Nihon Keizai Shimbun. The event was originally scheduled to be held in March, but was postponed due to the COVID-3 pandemic.
The venue was Muromachi Mitsui Hall & Conference on the third floor of Coredo Muromachi Terrace in Nihonbashi, Tokyo. There were seats available, but social distancing was observed and the number of attendees seemed a little low. Minister Aso delivered a video message, and many of the other speakers were present remotely.

All participants except for the moderator, Professor Sako of Waseda University, participated remotely. 
Professor Matsuo of Georgetown University came to Japan for this purpose and will be in quarantine for two weeks.

Naturally, they were remote participants from Spain, the US, and Canada, respectively. Irene was there at 3:20am, which was a crazy time, but she was dressed up and stylish. Maria, too, of course. In general, the male overseas panelists had messy hair, while the female panelists looked sharp.
However, these remote panels are bad for the heart. The sound from the remote side can be difficult to hear in the venue due to too much reverb, and the conditions are not good. Even before that, there are many worries, such as whether the call-in will be properly made and whether the line will be OK at that time.
As a result, I forgot to take screenshots of my session, hoping that the organizers would provide some photos and recordings soon.
I also participated in two other unconference sessions at Fin/Sum | BG2C, including one as a facilitator. The remote unconference was also a very interesting experience.
