Asama Maru
In December 1941, Japan declared war on the Allies. In May 1942, Japan and the US agreed to exchange interned diplomats and other citizens, chartering three ships—"Conte Verde" (known as "Teikyo Maru" while chartered), "Asama Maru" and "Gripsholm"—for this purpose. The "Conte Verde" and "Asama Maru" were sent by Japan, and the "Gripsholm" by the US. They met at Lourenco Marques, exchanged the internees and returned.
