The island is increasingly gaining international attention not only generally for its modern regional heritage, but also for the undisturbed housing complex remnants representative of the period from the Taishō period to the Shōwa period. It has become the frequent subject of discussion among enthusiasts for ruins.
Since the abandoned island has not been maintained, several buildings have already collapsed. Other existing buildings are subject to breakage. However, certain collapsed exterior walls have been restored with concrete.[citation needed]
While the island was owned by Mitsubishi Material up until 2002, it was voluntarily transferred to Takashima town. Currently, Nagasaki city, which absorbed Takashima town in 2005, exercises jurisdiction over the island. A small portion of the island was re-opened for tourism on April 22, 2009.[citation needed] A full re-opening of the island would require an enormous amount of money to make the premises safe, due to the aging of the buildings.
