From that we know now for sure is Kalafina will be at Japan Expo on Saturday (the 5th of July) for the Japan in Motion Event. If it is organized the same way like the past year, they will perform at this event only a few songs and perform a live another day.
From my point of view based on previous edition of Japan Expo, I think they would perform their full live either on Friday or Sunday but I am not quite sure. Unfortunately we still have to wait for Japan Expo staff gives the information or displays the planning.
However, this year is different from the previous ones in many things. First, the event will take place over 5 days and not 4 has it used to be the 6 previous one. This year, the "Comic' Con" part will not be there. By consequently, all the events are from the Japan Expo part. Which means more event, conference, live that the previous years.
Besides, this year we will have a true Hello Project! show with the coming of the Berryz Kôbô x °C-ute. But the live will be done the 3rd of July after the standard convention day and need a special ticket (different from the one for the convention).
So many things have changed but most of the people came principaly on Saturday and Sunday (and Thursday too) and I do not think it will different this year.
I think that it will have signing session with Kalafina because all the artists which have perform at Japan Expo also participated to signing session. The main question is : Will it be a "first arrive" type or a "lottery decided" signing session ?
Ah...maybe I should explain to you how the signing sessions work at Japan Expo. First at all, I am going to talk only about the ones organized by Japan Expo. The ones organized by labels or editor which exhibit may not follow the same principles.
In most of the cases, we have two kinds of signing sessions : "first arrive" and "lottery decided".
In the convention center, there is a place called "Point dédicaces". You have to go there and wait in the queue dedicated to the artist you wish get a signature with your ticket (the one used to enter the convention and that YOU MUST NOT TRASH).
- "first arrive" : the number of people who will be able to participate to the signing session is limited. So the first ones who arrived at the "Point dédicaces" and asked for participating the signing session are the ones who will get it.
- "lottery decided" : You participate at lottery game and get immediately the answer whether or not you will be able to participate to the signing session. But you can participate only once to the lottery (except people who have bought Platinum, Gold and Silver tickets).
Another point is that you are limited in the number of signing session to which participate a day. I do not remember how it is for standard tickets. I have to check it.
