Mariko Hayashi Tops Billboard Japan Book Hot 100 With New Essay Collection

Mariko Hayashi has clinched the premier position on the Billboard Japan Book Hot 100 (dated Aug. 20) with her reflective essay collection, 80-dai ni Naru to Taitei Bokeru ka Shinu. 70-dai wa Kamisama kara Ataerareta Tokubetsuna Jikan.

First published in May, the provocative title loosely translates to “Most People in Their 80s Face Dementia or Death: Your 70s Are a Divine Gift of Time.” Now 72, the prolific author offers candid reflections on navigating health, personal aesthetics, lifelong work, personal finance, social connections, and leisure. A surge in recent television guest appearances revitalized in-store retail demand, driving the title to the top of physical sales while generating consistent momentum across e-commerce, digital downloads, subscription services, and social engagement. Marking its peak in its 11th week on the survey, the release makes history as the very first shinsho—a standard compact, pocket-sized nonfiction paperback—to lead the comprehensive chart.

Holding strong at No. 2 is Volume 18 of Izumi Tsubaki’s popular manga series Monthly Girls’ Nozaki-kun (Gekkan Shoujo Nozaki-kun), which captured the runner-up spot in both physical shops and e-commerce platforms. Keigo Higashino’s 2023 mystery novel Anata ga Dareka wo Koroshita climbed to No. 3, buoyed by the release of its new mass-market paperback edition. The celebrated mystery writer, who passed away on July 23 at age 68, remains a dominant force on the survey, with Eien no Kioku resting at No. 6 and Hakucho to Komori (Guilt) Vol. 1 holding at No. 20.
