Six publishers of high school history textbooks are considering revising entries in their books about Japan's earliest stoneware, following Sunday's disclosure that a leading archaeologist had fabricated his discoveries of such artifacts.
The textbooks contain descriptions of stoneware unearthed at the Kamitakamori ruins in Tsukidate, Miyagi Prefecture, purportedly dating back as far as 700,000 years.
Shinichi Fujimura, 50, who served as deputy director of the Tohoku Paleolithic Institute, admitted Sunday that he buried stoneware in late October to make up the finds at the Kamitakamori ruins. He also said he similarly planted stoneware at the Soshinfudozaka ruins in Shintotsukawa, Hokkaido, in September.
