The Olympic and Paralympic Games will come to Tokyo in 2020. While many reports have focused solely on the hosting fees, I believe that it is more important to consider how the Games may give us an opportunity to change our lives and ways of thinking, and could bring a chance for Japanese people to mature socially. The ocean will be utilized as a venue for the Games, with the Open Water Swim to take place in the waters around Odaiba. However, as the water there is still far from being in a suitable condition for swimming, more cleanup efforts are needed. I hope that the water quality in Odaiba will see improvements by 2020.
