That was an unnoticed part of TOS for years for me. Finally I read that Takei wanted Sulu in "Naked Time" to be using a foil instead of a Katana blade because, in the future, culture had diversified enough so that Sulu's Asian background didn't influence his choices. (NuTrek changed this about Sulu when they gave him a Katana blade)
Making a Eurasian woman have a Hawaiian sounding name would also fit this thinking of more cultural diversity in the future.
