The Tokyo Olympic logo is a sign of blessings, luck and celebrations. It features a traditional Japanese knot called “MUSUBI” with five official colors of Olympics, turned into a colorful and attractive pattern of knotted strings used in Japan to decorate gifts.

The 2008 Summer Olympics will be held in Beijing, China. The emblem for Olympics 2008, entitled as the "Dancing Beijing", was first displayed in August 2003, in a ceremony attended by about 2000 people at Qi'niandian, the Hall of Prayer for Good Harvests in Beijing's Temple of Heaven. The emblem comprises a red seal with a calligraphic word for “jing”, the national capital, that weaves elements of traditional Chinese society with athletic features. The open arms of the calligraphic word represent the invitation of China to the world to share its culture. As a whole the “Dancing Beijing” represents mutual trust and an expression of self confidence, standing for the solemn yet sacred promise that Beijing has made to the world and humanity.

jagged emblem, based on the date 2012, comes in a series of shades of pink, blue, green and orange and will evolve in the run-up to the Games.
The word London and the Olympic rings are included in the first two digits of the new logo.
