The answer is the group B. Burakunim. They are a group of outcasts in the feudal era found at the very least of the Japanese social order. They were victims of discrimination and ostracism. They were defined with occupations considered impure or related to death.

The answer to above question should be Burakumin (B). They are outcasts in the Japanese social order during the Japanese feudal era. They are the "discriminated communities" and some are referred as non-humans. But this caste system has been abolished in 1869.

They showed the country that integration could be successful.
