Nikolai Ge's painting The Synhedrion Court, removed from exhibition in the C19 on the grounds that it insulted the Church, has been restored and is on display at the Tretyakov Gallery until 18 January (Grigori Revzin/Kommersant, in Russian).
The Bunkamura Museum of Art in Tokyo was informed by the Paris-based Marc Chagall Committee that the three works were not genuine because the painting techniques were dubious, museum spokesman Masao Kotani said.
Mr Kotani said the paintings - Portrait Of A Woman (1908), Family (1911-1912) and Fiddler (1917) - were lent by the Moscow Museum of Modern Art, which insisted the paintings were real.
"We are going to leave it to the two of them to discuss the paintings' authenticity," Mr Kotani said.
