During WW2, a Japanese Consul saved 6,000 Jews from the Holocaust by writing them all Visas to Japan even after the government told him not to.
During World War II, Chiune Sugihara, a Japanese diplomat posted as an acting consul in Lithuania, disobeyed instructions from his own Government and issued visas for Jews fleeing Nazi persecution.
Sugihara issued more than 2,000 transit visas to Jewish refugees in 1940, continuing to sign the travel documents even after the Japanese consulate was closed down and until his train pulled away from the station. Many of the visas were for entire families. As a result, it is estimated that Sugihara saved 6,000 Jews.
