Hashima Island is one of the strangest sights in Japan, a land that is full of unique novelties. Hashima Island is protected on all sides by tall sea walls. The island was originally bought by a corporation to mine coal from the deep sea. Tall concrete buildings and walls were built to protect the island residents and miners from sea storms. With the decline of coal, the island was abandoned for 35 years until urban explorers began illegally exploring the ruins. Urban explorers adore visiting the island, since it is a preserved record of early 20th century Japanese lifestyles. Some buildings have partially collapsed, allowing for a unique look at 20th century ruins.
