Oricon, a data compiling company specializing in providing data for the Japanese music/book industry, has announced the best-selling book rankings for the first half of 2019, which were compiled between November 19, 2018 and May 19, 2019.

Without any surprises, Eiichiro Oda's internationally popular series One Piece took first place in the manga sales ranking for 11 consecutive years since 2009 by still selling a huge 5,015,325 copies during the six month period, while Kaiu Shirai (story) and Posuka Demizu (art)'s The Promised Neverland jumped up to second from last year's eighth with 4,180,039 copies.

In the light novel section, Fuse's That Time I Got Reincarnated as a Slime became the top-selling seies. Last year's champion, Kugane Maruyama's Overlord, which has released no new volumes since April 2018, disappeared from the top 10. Meanwhile, the 21st volume of Reki Kawahara's Sword Art Online sold 239,946 copies, which was enough to make it the top-selling title in the overall bunko sales ranking including all genres. SAO is the first light novel series that dominated the ranking.
