The Tokyo Marathon International Friendship Run 2015 was held today at the Tokyo Waterfront City Symbol Promenade Park in Odaiba. This event is some sort of partner event to the Tokyo Marathon. I guess it was meant to introduce the overseas runners and their families to Japanese culture. It also provided an international running experience to the family members. The run was a 5-kilometer route around the Odaiba complex, which is a popular shopping, restaurant, and entertainment district.
