J Pop idols Ayumi Hamasaki, Kumi Koda and Ai Otsuka all had to cancel concerts last month because of the threat of Swine Flu.
Avex, the industry leading record label and management company decided to err on the side of safety to protect the public.
The concerts were expected to pull in at least an estimated 48,000 fans.
Rescheduled dates for the six shows in the Kansai (Western Japan) region have yet to be announced.
