"I am glad that readers overseas appear to have embraced it as well," Kuroyanagi said through Kodansha.

The best-selling book was first published in 1981, and a sequel issued in October has already surpassed the half-million mark. An animated movie of the original book, depicting her unconventional school life during the period around World War II, hit screens across Japan on Dec. 8.

Guinness World Records has also recognized her TV show "Tetsuko no Heya" (Tetsuko's Room) as having the most TV talk show episodes hosted by the same presenter.
