Japan Post Holdings Co. might sell the sites of four inns and four hospitals it operates to streamline operations as it prepares to go public in spring 2015, sources said.

Three of the resort sites are in Maizuru, Kyoto Prefecture, Kashiwazaki, Niigata Prefecture, and Shimabara, Nagasaki Prefecture, the sources said Friday. The three inns were demolished so that more earthquake-resistant structures could be built, but work has stalled since Japan Post reviewed their lack of profitability.

The site of the fourth inn, in the coastal town of Matsushima in Miyagi Prefecture, has been closed since the March 2011 tsunami crashed into it.

The four hospitals are located in the cities of Sendai, Niigata, Kobe and Osaka, according to the sources.

Other loss-making facilities may also be sold in Japan Post's restructuring process, the sources said. At present, the postal group operates 66 Kampo no Yado inns and 14 hospitals nationwide.
