Kuu do livestream concerts is 1 alternate possibility of her celebrating her 20th anniversary this year
It depends if she wants fans to pay for it or not
FLOWER FLOWER did their 1st livestream concert just last night which fans had to pay 3,000 Yen to watch the concert via e+
While last month , Kiyoharu did 2 back to back livestream concerts which fans had to pay either 7,000 Yen or 12,500 Yen to access the content online via ZAIKO
That's costly & it's as good as though you're attending a concert in Japan physically but the upside is that ZAIKO's video quality is probably the best out of all the streaming sites I've seen
ZAIKO's video quality is extremely good ie. Blu-ray which somewhat justifies the price and it doesn't lag unlike Nico Nico Nama & let alone SHOWROOM -_-
And I'm not surprised Kiyoharu is doing another round of livestream concerts via ZAIKO this coming Thurs & Fri and fans have to pay either 7,500 Yen or 13,000 Yen to access the content
