‘ONE PIECE CHOPPER’s Vol. 1’ Debuts at No. 1 on Billboard Japan Book Hot 100

Eiichiro Oda’s ONE PIECE CHOPPER’s Vol. 1 opens at No. 1 on the Billboard Japan Book Hot 100 released April 30.

The title is the debut volume of CHOPPER’s, a spinoff project centered on the character Chopper from Oda’s ONE PIECE. The book depicts the beloved doctor’s everyday life and outings in the real world, rendered in manga and illustration form. The title claimed No. 1 in both brick-and-mortar and e-commerce this week.

Last week’s No. 1, Ryo Asai’s In The Megachurch, slips to No. 2, scoring points across five metrics: No. 1 in social media, No. 4 in subscriptions, No. 11 in brick-and-mortar and top-300 placements in both EC and e-books. Debuting at No. 3 is Misaki Takamatsu’s Skip and Loafer Vol. 13, which hit No. 1 in e-books.

The week’s biggest mover is Asako Yuzuki’s BUTTER, which surged from outside the top 20 to No. 14 after improving its point totals in brick-and-mortar, subscriptions and social media. On April 22, Yuzuki announced that the title’s publishing rights are transferring from Shinchosha to Kawade Shobo Shinsha; a paperback edition is scheduled for release from the latter on June 15.
