‘That Time I Got Reincarnated as a Slime’ Vol. 31 Tops Billboard Japan Book Hot 100

Taiki Kawakami, Fuse, and Mitz Vah’s Tensei Shitara Suraimu Datta Ken (That Time I Got Reincarnated as a Slime) Vol. 31 rules this week’s Billboard Japan Book Hot 100, for the chart released Feb. 19.

The Billboard Japan Book Hot 100 is a comprehensive chart combining physical sales, e-books, library loans, subscription data, and social media activity.

Manga dominate the top five this week. At No. 1 is the latest volume of the popular “TenSura” light novel series’ comic adaptation, which leads both physical stores and e-books while coming in at No. 6 in EC (e-commerce). At No. 2 is Yumi Tamura’s Mystery to Iu Nakare (Don’t Call It Mystery) Vol. 16, whose live-action TV drama adaptation aired in 2022. A new story arc, the “Island Arc,” begins with this volume.

Tatsuki Fujimoto’s Chainsaw Man Vol. 23 holds in the top 3 after debuting at No. 2 last week, hitting No. 4 in both physical stores and e-books this week. Following are comic adaptations of works originating from the user-generated novel site Shosetsuka ni Naro, often referred to collectively as “Naro-kei,” including “Mugen Gacha” (Unlimited Gacha) and “Seventh Prince” series, both landing within the top 5.

Ryunosuke Matsushita’s Sci-Fi mystery suspense novel Ichijigen no Sashiki (Labyrinth of Hortensia and the Minotaur) continues to climb, rising from No. 15 last week to enter the top 10 for the first time. The book hits No. 8 as it holds at No. 3 on the social media metric for a second consecutive week, while physical-store sales have also improved for three straight weeks.
