How to be respectful towards Japanese friend who is grieving a loss?

I have a friend from my previous job whose family lives in Japan and I remembered she mentioned one of her parents was ill when we worked together. Recently I invited her to my birthday but she said she was in Japan, so we chatted a bit and then I asked how her family is doing. She said "it's not good news" and not much more. I'm assuming this means someone is very sick or has passed.

I know death, especially that of a closed loved one, is such a sensitive subject and each culture and language has ways of processing it. I want to be respectful and supportive in my response and am wondering if anyone has advice <3 ty
