 In 1925 , Maeda became involved with helping settle Japanese immigrants near Tome @-@ açú , a Japanese @-@ owned company town in Pará , Brazil . This was part of a large tract in the Amazon forest set aside for Japanese settlement by the Brazilian government . The crops grown by the Japanese were not popular with the Brazilians , and the Japanese investors eventually gave up on the project . Maeda also continued teaching judo , now mostly to the children of Japanese immigrants . Consequently , in 1929 , the Kodokan promoted him to 6th dan , and on November 27 , 1941 , to 7th dan . Maeda never knew of this final promotion , because he died in Belém on November 28 , 1941 . The cause of death was kidney disease .
