Fireworks explosion kills three women on Oahu

[Durian Fiend]

Let me try asking my question another way.
If one of the arguments that everyone should get to blow off fireworks in Hawaii is because it’s cultural and part of the Hawaiian heritage, around what date give or take a decade or two did the average Hawaiian resident have the wherewithal and resources to buy and blow off fireworks?  

There was a canon in Hawaii in the 1800’s too, but the average guy didn’t have one to fire off on his birthday.

I think it was the large influx of Japanese immigrants in the later 1800s that was mostly responsible for fireworks becoming popular in the state.
Of course, it wouldn't be until some time in the 20th century when the average resident would have easy access to buying and utilizing them.
So the cultural argument seems weak to me.
