Japanese Prime Minister Shinzo Abe has visited his father's grave while waiting for Russian President Vladimir Putin to arrive for a two-day summit.

Abe said Thursday on his Facebook page that he paid respects at the grave in his ancestral hometown of Nagato in western Japan. Putin's flight was delayed.

Abe wrote, "Looks like the president's arrival is being delayed, I used the time to visit the grave and reported to my father who devoted his late career to push for a peace treaty."

His father is former Foreign Minister Shintaro Abe, who pushed for resolution of a territorial dispute between the two countries.

During the talks Thursday and Friday, Abe hopes to make progress on the dispute over islands that kept Japan and Russia from signing a peace treaty formally ending wartime hostilities.
