I have a few questions about Okinawa Japan?

Question:

1. How big are the houses? (I've heard that houses in Japan are small)
2. Is it city-like or more country-side? Like is there alot of nature or more modernized buildings and houses?
3. If I am Puerto Rican and come there every summer, my mother is Japanese, would I be accepted as Japanese?
4. What is the weather like at this time? (May/June)
Thanks for reading and hopefully answering. Its research for a story I'm writing :)

Answer:

3, It depends on if you speak Japanese as much as other Japanese do, and if you know Japanese custom.

Since you are asking this question in English, I guess you don't speak so much Japanese?
