Yes, Hawaiʻi is a US state, but it is the most isolated land mass in the world. In the center of the Pacific it has influence from all it's neighbors, including island cultures you probably never heard of, like Chuuk and Palau, along with Japan, Korea, China, New Zealand, Australia, and so many others.
In addition if you spend the time to research the history of Hawaiʻi you will find strong roots of a kingdom which, like Kilauea, lives just under the surface and has a strong influence on life here. As such it is best to treat the culture with as much respect as any foreign country.
Here is rundown of Island culture.
A land and people rich in legends and respect for the islands they steward (not own, steward). According to legend the land itself is the stillborn older brother of the Hawaiians, they treat it like family, caring for it as it cares for them. It is precious, thus permission is asked whenever a plant is used, and preferably returned to where it was harvested when done.
Slightly different from the college...
According to 2000 census data.
- Take your shoes off before entering a home and line them up with the others.
- "Auntie" or "Uncle" rather than Mr. or Mrs. when addressing an elder
- When visiting someone for the first time, bring a small gift for the host. Food is ideal.
- A hug or kiss on the cheek is a form of greeting
- Don't touch the honu (sea turtles) - endangered species
Hilo is a sleepy little town whose vendors work to live, rather than live to work.
Don't be surprised if you come up to your favorite bakery and there's a sign which says, "Traveling- be back next month", (though you're probably friends with the owner and you guys have talked story about their upcoming trip). Use Siri or the internet to check hours if you want a late night snack, because there's maybe 3 locations which are open 24hrs. In addition weekends are limited hours compared to the mainland, and shops tend to shut down around dinner time.
When you play around the island remember- you don't know if you're running into tourists, locals, or multi-millionaires. They are all dressed the same, casual, and maybe a little ruffled by the elements. Treat everyone with kindness. And being a prime vacation spot one of your friends may have a cousin who has a vacation home near by and works for Tesla, or Disney or some other big company.
It truly is "a small world" on these islands.
Everyone is related to some degree, or is tightly networked. This extends across the islands, and people rely heavily on reference checking. So the good news, if you build a strong network there's a good chance you can find a basic job or place to live. Bad news is, if bridges are being burnt often, the entire island chain will know who the pyromaniac is.
Lesson: treat everyone with respect.
