Organizers and official partners of the Tokyo Olympic and Paralympic Games put up decorations in parts of the city and held events at Haneda airport Tuesday, one day before Japan starts the one-year countdown to the opening of the games.

In a project dubbed "Nihonbashi City Dressing," Olympic organizers and major real estate developer Mitsui Fudosan Co. decorated the streets of the business and commercial district with flags, curtains and massive posters of the Olympic logo and athletes expected to compete in the games.

Pieces of art depicting swimmers and the Olympic rings were installed on street corners, while giant posters of promising Japanese athletes, including climber Miho Nonaka, were splashed across glass windows of businesses.
