"The Japanese government plans to register the remote islands as part of its state property to enhance their management" Xinhua quoted Minister for Ocean Policy and Territorial Issues Ichita Yamamoto as saying at a press conference.
The islands are among 400 unnamed islands by the Japanese government.
Ichita said that nearly 100 of them have already been registered as state property as they form part of what Japan sees as its broader exclusive economic zone, in which Japan conducts marine explorations and other research activities, but conceded that a great deal about the islands was still "unknown".
"I've been criticised by some opposition party members for not yet having all the information on all the remote islands and I plan to speed up the project as much as possible and it is my strong wish that the survey be completed by June," Yamamoto said.
Yamamoto added that under Japanese law the 280 ownerless islands are properties of the state and their registration as such will enable the government to effectively manage them.
Tuesday's announcement comes as Japan is embroiled in territorial disputes with neighbouring countries, including China and South Korea, that have caused tensions in the region.
In September 2012, Japan claimed three of the Diaoyu islands, which are also claimed by China in the East China Sea, sparking mass protests in China. The islands continue to be central to a maritime standoff and deteriorating diplomatic ties between the two countries.
