Seoul (CNN)Kim Bok-dong was brought to the Japanese Embassy in Seoul one last time Friday.
Her casket was driven slowly through the South Korean capital in a funeral procession attended by hundreds of mourners. Supporters braved sub-zero temperatures to say farewell to one of the country's best known "comfort women." A wartime euphemism for women and girls, like Kim, who were forced into providing sexual services for Japanese soldiers before and during World War II.
Many mourners held banners reading "Our hero Kim Bok-dong" and chanted anti-Japan slogans.
On Friday, an emotional ceremony was held in the street next to the bronze statue of a Korean girl that sits watch in front of the Japanese Embassy, a symbol of up to 200,000 women from South Korea and other Asian countries experts say were forced into Japanese wartime brothels.
A beloved leader of the "comfort women" protest movement, Kim's supporters say she died as she lived, her final words a statement of rage against Japan, calling for the fight for justice to go on.
While Japan claims the issue is resolved by previous agreements and apologies, South Korean activists say not enough has been done -- they demand a more formal apology and reparations from Tokyo.
"Kim taught us lessons about what peace is, what human rights are and what it is to hug the weak and the injured," said Yoon Mi-hyang, president of the Korean Council for the Women Drafted for Military Sexual Slavery by Japan.
'I can't put into words the scars it left'
According to Kim, Japanese soldiers came to her home when she was 14, telling her she would be sent away from Korea to help with the war effort -- South Korea was a colony of Japan at the time, and Kim thought she was being sent to a factory.
Over the next eight years, Kim was moved around half a dozen countries as the Japanese imperial forces spread out across Asia.
"Every Sunday, soldiers came to the brothel from 8 a.m. to 5 p.m.," Kim told CNN in an interview in 2012. "On Saturday from noon until 5 p.m., plus weekdays. I could not stand at the end of the weekend, I was physically broken."
After the war, Kim traveled the world again, this time of her own volition, to tell her story and raise awareness of the "comfort women" issue. She even visited Japan.
She said she could never have a child because of her experience and Japan had ruined her life.
"In my old age, I would not have a single person who could call me mother, I could not have a child," Kim added.
Apologies and reparations
Kim and her supporters repeatedly have called for the Japanese government to admit the wartime brothels were state-sanctioned. Some ultra-conservatives in Japan claim the women worked voluntarily for money.
"I want Japan to repent their wrongdoings and apologize," she said in 2012. "Japan is saying that it was the civilians who committed such acts and they did not drag people forcefully, but people voluntarily went with then, which is a lie."
Japanese prime ministers have apologized in the past, and Tokyo believed the issue was settled in 1965 as part of an agreement to normalize relations between the two countries.
Another landmark deal reached in 2015 saw another apology and a pledge of $8 million for a foundation to support the surviving "comfort women."
"I think we did our duty for the current generation by reaching this final and irreversible resolution before the end of the 70th year of the war," Japanese Prime Minister Shinzo Abe said at the time.
But the deal proved to be neither final nor irreversible as former "comfort women" rejected it, saying they had not been consulted.
