A large-sized Olympic rings monument has today been installed at Odaiba Marine Park, as the countdown to Tokyo 2020 continues.

The monument, which was built in Yokohama and is 32.6 metres wide and stands 15.3 metres tall, was brought by a salvage barge to the Tokyo waterfront area and is floating on a concrete platform.

It is one of the Tokyo Metropolitan Government's key initiatives for dressing up the city to build up a "festive atmosphere" for residents, visitors and spectators around the world.

Odaiba Marine Park, the site for the marathon swimming and triathlon events at Tokyo 2020, offers panoramic views of the Japanese capital's skyline, overlooking Rainbow Bridge and Tokyo Tower.

The five interlocking rings will be officially inaugurated on the evening of January 24, exactly six months before the Opening Ceremony of the Tokyo 2020 Olympics.

The event will include the first lighting of the monument and celebratory fireworks.

The Tokyo 2020 Olympics are due to take place from July 24 to August 9.

During the Tokyo 2020 Paralympic Games, running from August 25 to September 6, the monument will be replaced with the Paralympic symbol.
