Yep, it's definitely confirmed, I'm going back to Tokyo for a flying visit - flying out on Saturday 23rd, arriving Sunday morning, then back home on Tuesday morning, and back into work on the Wednesday, thus only using up my last two remaining holiday days of the financial year. I think it's fair to say that jetlag will be a problem, but I'm sure I'll be up to whatever memory stunts they're wanting me to perform in the studio.
The weather is apparently really quite nice in Tokyo at the moment, so hopefully it'll be a nice change from the ice and snow and nastiness over here. And even if it's not, yay! Japan! Again! For free! Being the World Memory Champion is great!
