Sakura spots

Hi I’ll be in Okinawa 19-28Jan and I didn’t realise Sakura bloomed so early in this part of Japan so I got a little excited. Tbh when I lived in Japan, my favourite Sakura spot was none of those famous ones full of tourists but just a little mountain in my inaka which was lined with Sakura blossoms as I drove up. I was wondering if anyone has Sakura spot recommendations other than Mt Yaedake (I’m hoping to visit 20 or 21st I assume it might be crowded) for daytime

sakura viewing (is Nakajin castle nice for daytime viewing too? I keep reading about night blossoms). Thank you!
