I wrote "comfort women" between quotation marks as I personally find that the words has euphemistic qualities

Well, don't write it with quotation marks. It does have euphemistic qualities - it's a translation of the Japanese word "ianfu," a word that literally means "comfort women" and is a Japanese euphemism for prostitute. The Korean term is wianbu (위안부) which translates as "comfort women". If you write it with quotation marks, the implication could be that you think another term, a more direct and pejorative term would be appropriate. If you're Japanese and that's your position, okay. But if you're just trying to be politically correct, the accepted term in Korean and in English is "comfort women."

As far as why they receive so much more attention, that's a question that really cannot be answered here without violating the 20 year rule. The basic rundown is that after World War 2 ended and the Japanese surrendered, the women returned home and didn't talk about their experiences. They were ashamed and/or embarrassed. Some of these women had gone voluntarily, being told that they would be getting legitimate work - factory jobs, nursing jobs, etc, and were then forced into prostitution. Some were kidnapped. Either way, it's not something they wanted to discuss. It wasn't until 1993 and the Kono Statement that the Japanese admitted that Korean women were forced into prostitution. Around this time is when the women who were still alive started to speak out on the issue. Since the Japanese had admitted what had happened, they could speak out as victims instead of willing participants.

And here is where we hit the 20 year rule. The short version is that the Japanese government, under successive governments since Kono, has backpedaled and wavered on it's admissions and the comfort women, now out in the open, have taken a stand.

As to why there no attention compared to the forced labourers or A-Bomb victims, that's because they've already been paid off. It's easy to call a woman a prostitute and say she did it voluntarily if she isn't going to come forward and counter the argument, but what shame or embarrassment is there for factory workers or coal miners? The Korean government reached a settlement with the Japanese government over compensation in 1965. The A-bomb victims are also victims in the eyes of the Japanese and they have a statue for them in Hiroshima. The Koreans can't really complain when the Japanese have built a statue and count them as victims, too.

TLDR - the comfort women have, in their minds, not been properly apologized to. When the forced labourers were being compensated, the comfort women were silent. It wasn't until the Kono Statement that the remaining women were ready/willing to come into the light. For more information, read up on the situation on your own since it falls with in the last 20 years.

Here is a photo of the memorial for Korean bombing victims. I took this photo in July 2014 while traveling through Hiroshima. This memorial sits probably a few dozen meters to the south of the burial mound in the Peace Park.

I don't have a photo of the comfort women statue in Seoul. It sits in front of the Japanese Embassy, which is surrounded by guards and protesters. I've just never felt comfortable snapping a photo there. But, it's easy enough to find a photo of, and if you read up more on the past 20 years, I'm sure you'll find it.
