The Defense Ministry is thinking of stationing F-15 fighter jets at a remote airport halfway from Naha to Taiwan to speed up its response to airspace incursions by China near the disputed Senkaku Islands, government sources said Monday.

The planes would be stationed on Shimojijima Island, which is much closer to the Japan-administered Senkakus, which China claims as the Diaoyu, than to Okinawa's prefectural capital Naha, where the Air Self-Defense Force's F-15s are based.

But since Shimojijima Airport is not equipped for military use, the ministry would have to make several modifications before shifting the fighters over from Okinawa Island, the sources said. The island is right next to better known Miyakojima Island.
