A huge Olympic rings monument in Tokyo Bay has been temporarily removed for safety checks.
The floating monument is 33 meters wide and 15 meters high. It was installed in January on the water in Odaiba Marine Park, one of Tokyo's Olympic venues.
Japan's Air Self-Defense Force aerobatic display team has practiced skywriting the Olympic rings to prepare for a ceremony marking the arrival of the Tokyo Games' torch.
The team practiced on Friday, six months before the start of the Olympics.
