If you mean the rule during the first half of the twentieth century, it was in 1945, when WWII ended. If there was any other Japanese rule of Korea, I can't help you on that.

Korea was occupied by the Japanese in 1905 at the end of the Russo-Japanese War.

Korea is liberated from Japanese rule. Korea has beem separated into two countries, the Soviet-backed Democratic People's Republic of Korea and the pro-American Republic of Korea.

Taiwan under Japanese rule was created in 1895.
