“A lot of Hawaii is owned by the Japanese and the natives are Polynesian so that could make it a part of Asia!”
There’s a LOT of Phillipino’s in Kauai.
If you are asking why Filipino instead of Philipino when the Philippines is spelled with a ph, the answer lies with the old name for Philippines. When the country was first colonized by Spain, they give the archipelago the name Las Islas Filipinas and its inhabitants Filipinos. When it was Americans turn to colonize the country, it was renamed Philippines. However, the term Filipino stuck.
