Umi ni Nemuru Diamond

A grand tale of love, friendship, and family spanning 70 years, set between the coal industry boom in Hashima Island, Nagasaki Prefecture, from 1955 and modern-day Tokyo. The story weaves together the bonds of family, human interactions, and tales of youth and love during the post-war recovery and the high-growth economic period, a time of “nothing much but full of dreams and vitality.” (Source: Japanese = tbs.co.jp || Translation = MyDramaList)
