A key executive of a group spearheading a recall petition against Aichi Gov. Hideaki Omura, in relation to a 2019 exhibition, has admitted to forging finger stamps and signatures under instructions from the group leader.

In an exclusive interview with the Chunichi Shimbun, Takeshi Yamada, 52, a member of Tokoname Municipal Assembly who served as an executive in the recall group, admitted his deep involvement in the incident. He resigned his membership of the assembly on April 15.

"Following secretary-general Takahiro Tanaka's instructions, I finger stamped alongside many signatures written by the same person in Nagoya during late October to early November last year," said Yamada.
