Hashima Island had been used for undersea mining since 1887. More than 600m² wide, the size results of bank up earth and a massive wall which protects the island from swell. In 1916 Mitsubishi took over the mining and built Japans first ferroconcrete multistorey building. During WW2 the japanese workers got replaced by korean and chinese forced laborers, while lots of them didn't survive the bad working conditions. In the 50s Hashima got the highest population of the world with more than 80000 inhabitants per km² and was equipped with schools, stores, a hospital, leisure facilities, post office and police. Because of the shortage of space, parts of the infrastructure had to be built underground. Farming took place on the roofs. With the closure of mining in 1974 the island was abandoned. Transportation of personal belongings to the mainland was too expensive for many people, so that many things got left behind. Today the buildings are in desolate condition and some had already collapsed. Hashima island is considered as memorial for ruthless exploitation in Japan.

I saw a documentary on this place a few years ago and have always wanted to see it. I'm amazed how much it's deteriorated. The salt in the air isn't being kind to that concrete. I'll bet in another 40 years there won't be much left standing.

You're fortunate to have been able to see it and thank you for sharing - great job!

Always helps set the mood with some background story.
Nice video!
