UPDATE 9/14/23: Just announced is a separate lottery for overseas fans. Colloquially called the "gaijin (foreigner) lotto," it is specifically targeted for fans not in Japan. You do not need an eplus account for this. I attended Aquors 4th Live at the Tokyo Dome back in 2018 thanks to this lottery, and the seats were great, so if you've got the money, go for it. Applications begin tomorrow, 9/15/23.
It does cost more than just the tickets on their own, given that it includes a hotel stay for two or three nights (depending on which plan you choose), but if you are not versed in the ways of eplus, this is your best shot. You're also only having to face off with other gaijins who can pay for a trip overseas, so your overall competition is much less in number than the eplus lottery.
A few notes about the gaijin lotto: you do not get to pick what hotel you are assigned. The hotels are more expensive than other hotels you could book for yourself. The hotels are spread around Tokyo so you could have a short trip or it could be on the longer side. You can either apply for yourself and one other person or by yourself.
The seats will probably be pretty good. For 4th Live, you were either on the floor itself or in the stand near where the moving ship stage traveled to. Given the size of the dome, that meant you were very close to the action. I'd expect something similar for Ijigen.
Here's the details:
Plan A - both the 12/9 and 12/10 shows. 102000 yen for one person (approx $690 at press time), 96000 yen per person for two ($653)
Plan B - only 12/9 show. 74000 yen for one person (approx $500 at press time), 70000 yen per person for two ($475)
Plan C - only 12/10 show. 74000 yen for one person (approx $500 at press time), 70000 yen per person for two ($475)
Minimum number of participants
Plan A: 150 participants
Plan B: 100 participants
Plan C: 100 participants
So if they don't hit these numbers, it's a no go.
To apply for the overseas lottery, please go here for information. The direct link to the application website is here. The overseas lottery will be open from 9/15/23 to 9/26/23. The eplus lottery is still open until the 25th in Japan.
