It's such a shame that I couldn't go :( I'm interested in going to Japan, let alone attend this conference. If I remember correctly, Craig Wright did not have a talk scheduled, which is funnily ironic to me, as I'm pretty sure he is Satoshi :P
Edit: My apologies, he actually did do a talk. Hour 5:20:00 on the event's livestream. That was a nice surprise.
