Okinawa, formerly the Kingdom of the Ryukyus, was annexed by Meiji Era Japan in 1879. During the previous 500 years, the kingdom had maintained close ties with China, and to this day much of the culture displays a strong Chinese influence. This includes Chinese cooking and clothing, dragon-boat racing and, perhaps most importantly, the lunar calendar and the 12 signs of the Chinese zodiac.
