'I feel I have lost the ability to have a definite opinion, in terms of people, and about myself," says the Japanese installation artist Tabaimo. It is a surprising admission from someone who first received international acclaim for what were seen as perceptive and cutting social commentaries on modern Japan. But Tabaimo has dealt with the change in stride.

"I have taken this new part of myself that is unsure and shaky, accepted it and put it into my work," she told The Japan Times in a recent interview.

Her latest works on display at "Yoro-yoron," an exhibition at the Hara Museum till Aug. 27 -- three installations and sketches for the serialized novel "Akunin" by Shuichi Yoshida -- are definitely ambiguous, as well as being her most personal and challenging ones to date.
