I'm saying that I believe the Hawaii state codes include statistical codes for Korean and Puerto Rican. And it is possible this table from the state of Hawaii reflects those codes.
We know for certain that the Hawaiians code for Caucasian is 1, if that is a 2 and not a 7, then 2 is Hawaiian and 3 is part-Hawaiian. So the first three entries on the table match what would be Hawaiian coding scheme.
The only question is do the other races listed in the table line up.
A copy of Virginia Sunahara's death certificate should list her race (Japanese/Korean). I wonder if they code those.

I don’t have any guess as to what those local codes may or not not have been.
My own way of thinking is that unless there is a manual found, it is useless to guess.
Interesting to wonder about, useless to guess.
