The a-nation festival of Avex artists is set to embark on a summer tour of Japan for the eighth time.

J-pop chart-toppers Ayumi Hamasaki and Kumi Koda will once again headline the line-up, which will also include TRF, Every Little Thing, Do As Infinity, Ai Otsuka, AAA, Girl Next Door, Ami Suzuki, Touhou Shinki and others.

The festival is produced by Avex Live Creative, a wholly-owned subsidiary of the Avex Group. It will hold eight shows throughout Japan in August, including two in Tokyo and two in Osaka at stadiums with capacities of 50,000.

The major confectionary company Morinaga is once again the title sponsor, with their Winta in Jelly drinkable jello product included in the official festival name.

Lawson convenience stores will also participate as a sponsor and the tickets will be available at their stores, as well all nationwide ticketsellers. They go on sale May 8.

Avex projects total attendance for the eight shows to be between 200,000-250,000.
