A UNESCO committee reviewing nominations for its World Heritage list will resume its screening process on Saturday.
The three-day meeting began on Friday in the Azerbaijani capital of Baku to screen 35 natural and cultural heritage sites, nominated by members of the UN body.
The committee studied eight proposals on the first day. A Japanese nomination is scheduled to be considered on Saturday.
Japan proposed a group of ancient burial mounds in the western prefecture of Osaka.
The Mozu-Furuichi Tumulus Clusters consist of 49 mounds built between the late fourth and fifth centuries.
Among them is a keyhole-shaped tomb, which the Imperial Household Agency considers to be the mausoleum of Emperor Nintoku.
It is one of the largest of its kind in the world, measuring 486 meters in length.
The Mozu-Furuichi Tumulus Clusters are widely expected to be added to the World Heritage list, as a UNESCO advisory body recommended their inclusion back in May.
