In order to leave the territory of the Lithuanian Soviet Socialist Republic, the war refugees needed to obtain transit visas, which could be issued by the Japanese Consul General Chiune Sugihara. Seeing a bunch of people lined up at the gate of the Consulate, Mr. Sugihara accepted a 5-person delegation led by Zerach Warhaftig, who told Mr. Sugihara about the situation in Poland and expressed the request for transit visas. Mr. Sugihara agreed to issue the visas on a condition that the people promised not to stay in Japan and proved their Polish citizenship. In the summer of 1940, when most of the foreign consulates had been already closed, the Dutch Honorary Consul Jan Zwartendijk, having the permission from his chief L. P. J. de Decker, agreed to issue the so-called “Curaçao visas”, which showed the Caribbean islands as the final destination of the war refugees. Having obtained the visas, the refugees still needed to get permissions to leave the country from the Bolshevik administration. After that they just needed to buy a Trans-Siberian Railway ticket and were fully set for the long journey.
