Why is Tokyo Marathon called the best marathon in the world?

The reason why Tokyo Marathon is called the best marathon is as follows: The Tokyo Marathon, which started in February 2007, is a large-scale city marathon with 35,000 participants, including invited contestants from home and abroad, passing through the scenic spots in downtown Tokyo, such as the Imperial Palace, Ginza and Asakusa. There will be many touching scenes beyond imagination on the day of the game, and there will be constant unity along the way. Participants and volunteers, as well as the audience along the way, will be closely integrated, and the whole of Tokyo will be integrated into one, becoming a permanent record day in the history of marathon. Tokyo Marathon was included in the six Grand Slam World Marathon in 20 13, and it is the youngest event in the six Grand Slam World Marathon. (Others are London Marathon, Berlin Marathon, Chicago Marathon, New York Marathon and Boston Marathon). I hope I can help you.
