Business don't exist to respect or care about people they exist to generate profit so the idea of a business "respecting" something is not even realistic.
The law is what outlines what are the limits and guarantees the basics rights to everyone.

People work at businesses, and those people make decisions that are influenced by their personal feelings. In a free market people will boycott them for doing bad things. Racist businesses being outted, receiving bad press and losing revenue - in this scenario it sounds like the japanese are okay with it. Being respectful is profitable.

You claim that the government of Japan does not have the power to bestow citizenship on individuals?
