I'm not complaining, but since it appears to be the same in both languages, isn't it a littke redundant on its own?

This is extremely redundant, and requires no translation, as it is a place name (proper noun). That's like asking "What is Berlin in English?"

Isn't Oahu the most tourist attracted state, as well as the most populated? When I was small (I was born there and lived for 9 yrs.), I remember every bit of the island was covered in tourists. It was hard for the locals to get by without running into tourists.
