how to watch?
- if you live in Japan you can buy a ticket and go watch them in person
- if you want to watch it online you can do so via a paid live stream susbscription (available even outside Japan)
- you can wait a few weeks for the performances to pop up at Youtube or bilibili
where are my favs?
while the line up is "almost" complete they are likely to announce a few more acts, so there is a chance, its worth mention that its pretty packed already so i wouldn't get my hopes high
for more info
