On February 8th, 1919, 600 Korean students who were studying in Japan walked out on to the streets of Tokyo and shouted cheers for Korea's independence.
They read out a declaration justifying Korea's independence and expressed their determination to fight against rule by Imperial Japan.
That declaration was a catalyst for the historic March 1st Independence Movement that occurred a few weeks later.
On Friday, to celebrate the February 8th declaration, commemorations were held at the Korean YMCA buildings in Tokyo and Seoul.
The event in Tokyo was attended by around 250 people, including the South Korean minister of Patriots and Veterans Affairs, Pi Woo-jin .
The ceremony at the YMCA in downtown Seoul was attended by around 400 people.
At the event in Tokyo, the head of the Patriots and Veterans Affairs Ministry expressed her deepest respect for those who participated in the February 8th Independence Declaration and helped create today's Republic of Korea.
She also visited several locations in Japan important to the independence movement.
Those included the sites of two failed attempts by Korean activists to assassinate the Japanese emperor using grenades -- one in 1924 by Kim Ji-seop and Seo Sung-han , and another famous attempt in 1931 by Lee Bong-chang for which he was hanged.
