Japanese nationalism
In Japan, the Mukyōkai members are perhaps best known for speaking out against social injustices. They were one of the groups to take positions against Japanese nationalism and militarism in the 1930s and '40s, and remain today strong advocates for pacifism. In the United States the group is often mentioned in relation to human rights activist Gordon Hirabayashi, a practicing Quaker who was born into an immigrated Mukyōkai family in the United States.
