History of Okinawa
1. It was not part of Japan until Edo period.

Today, we all know Okinawa as the southern most prefecture of Japan, but do you know it was not part of Japan until the Edo period? The different islands littered around the region were unified under Ryukyu Kingdom. However, the invasion of Ryukyu Kingdom by forces of the Japanese feudal domain of Satsuma in 1609 marked the Ryukyu Kingdom’s status as a vassal state under Satsuma.

2. Okinawan language is a Japanese dialect now

Okinawan was never a spoken Japanese language in the earlier days. The official language of the Ryukyu Kingdom was a Shuri-Naha variant, which is labelled as a dialect now by the UNESCO Atlas of the World’s Languages. This language is often referred to as Okinawan dialect within the Japanese context.

3. U.S. still holds 25 per cent of Okinawa’s land

History buffs would be familiar with the Battle of Okinawa. Near the end of World War II, the US Army and Marine Corps invaded Okinawa in order to fight Japan by cutting off their communications. US troops had remained in Okinawa since. Although Okinawa was returned to Japan in 1972, 25 per cent of the troops still remain there now.

4. Longevity myth in Okinawa

There have been many researches and debates about Okinawa having the highest life expectancy because of its longevity leaves. But this myth remains to be unravelled.
