Limited Edition

Quick Japan Zoukan WACK na Hon (クイック・ジャパン増刊 WACKな本; Quick Japan's Special Issue WACK Book) is a book released on October 20th, 2018. It contains interviews and photography of WACK members and staff.

To mark this special edition of Quick Japan, BiS, BiSH, GANG PARADE and EMPiRE took part in the first "WACK Competitive Sports Test".

In addition to the four core groups, the book also features interviews with WAgg, WACK staff and Watanabe Junnosuke.

BiS, BiSH, GANG PARADE and EMPiRE all belong to WACK, totaling in 31 members! The decisive battle of honour to determine rewards and prizes!

2018 saw BiSH, growing with rapid momentum, immediately sell out Yokohama Area, at its full capacity of 1.2 million. 

After hold events like the ‘Apologise First’ campaign that featured adverts across the SHIBUYA109 building, and releasing one-day albums costing a mere 300 yen, WACK set out a plan to hold an epic battle in a magazine to confirm their charms and continue to rise to the top of the idol world. 

We decided on rewards as we put these groups through their paces, judging them on physical strength, lyric writing, music composing, and, costuming. GANG PARADE, BiS, and EMPiRE all aim to further the game, but what will their results be after facing the very group that’s propelling WACK’s success, BiSH…!

This issue will not just contain interviews with all the members, of course, it will also feature interviews with WAgg, the training group that debuted this September, all label staff, WACK representative director Watanabe Junnosuke, among others. There will also be interviews will WACK staff members who have helped them reach to this point of success.
