Tokara Islands
Mention is made in the "Shoku Nihongi" under an entry for the year 699 of an island called “Tokan” ( 度感 ), which is usually identified with Tokara, together with the islands of Tane, Yaku and Amami, although “Tokan” is also sometimes identified with Tokunoshima, an island approximately away. However, an entry in the earlier "Nihon Shoki" for the year 654 mentions a "Tokara Country" ( 吐火罗国, Tokara no kuni ), but is in reference to Tukhāra, the land of the Tocharians, and has nothing to do with the Tokara Islands. During the 15th and 16th centuries, the islands came under the control of the Shimazu clan of Satsuma Domain and the Ryukyu Kingdom. Ryukyu ceded its territory in the Tokara Islands to Satsuma in 1611, which was confirmed by the Tokugawa Shogunate in 1624.
