The Japanese homeland is Japan, the Portuguese homeland, Portugal; the Chinese homeland is China, etc. etc. America is a polyglot of immigrants, except for its indigenous peoples.  All were immigrants of their own volition, from a homeland to which they could always return. Native Hawaiians have as solid a claim to indigenous status as any other indigenous people on the planet; Hawaii is their homeland, they have no place else to go if they don't want to be an immigrant. Act 57, sec. 30 of the 1896 Laws of the Republic of Hawaiʻi mandated English as the medium of instruction. It was not an outright ban, but permission was required to speak another language and its mandate, along with corporal punishment, was strictly enforced. I have firsthand experience of this because as a child, as I was whipped in the classroom by a Japanese teacher for speaking Hawaiian. Thereafter, my parents forbade my grandmother from speaking Hawaiian to me. You cannot erase the truth.
