I really appreciate this introduction to Liuchiu-China relations; thanks to Rob for recounting some history that demands more attention and Jim for posting it.
Guburii sabitan (you’re welcome), and niffee debiru (thank you) for the kind words. Kajiwara describes himself as “both Native Okinawan and a Hawaiian national.” Subscribe to his YouTube channel and log in to his website. -Jim
