Tragedy / Disaster Movies

Please recommend me some KR/JP Movies with tragic / disaster theme where there are survivors, someone dies and casts supports each other. Notable Examples: Titanic, The Day After Tomorrow. I'd like to watch 'The Tower' (f. Son Ye Jin) but it was just recently showed on cinemas and I could only rely on the fastest sub and the raw movie by next year. Edited; Watched List (Thanks for Everyone who recommended these movies) Haeundae Deranged

Maybe... Deranged?
