In 1932, Sugihara was transferred to the Division of Foreign Affairs of Manzhouguo (Manchukuo) and was involved in negotiations with the Soviet Union for the transfer of the Eastern Chinese Railway. He then returned to the Ministry of Foreign Affairs in Tokyo. After working in the ministry's Personnel Section and the Information Bureau, he was assigned in 1937 as a secretary and interpreter of legation in Helsinki, Finland.
Two years later, Sugihara was assigned as a vice consul to the Japanese consulate in Kaunas, Lithuania, where he was acting consul. In July 1940, as the annexation of the Baltic countries to the Soviet Union loomed, many refugees (most of them Jews who had escaped from Poland) asked Sugihara for Japanese transit visas to escape from Lithuania. Sugihara took personal responsibility for issuing visas until the end of August. As a result, more than 6,000 Jewish refugees were saved.
Sugihara then worked in the Japanese consulates in Praha and in Königsberg and in the Japanese legation in Romania. After internment following the end of the war, Sugihara returned to Japan. He resigned from the diplomatic service in 1947. In 1978, the Israeli government honored him with a medal for his services in saving the lives of Jews during World War II. The government also bestowed on him Israel's highest honor as "Righteous among Nations." Sugihara died on 31 July 1986, at his home near Tokyo.
