London’s Mayor Boris Johnson (front right) collides with 10-year-old Toki Sekiguchi during a game of Street Rugby with a group of Japanese children outside the Tokyo Square Gardens building yesterday. The game was held with schoolchildren, the Street Rugby Alliance and the Nihonbashi, Yaesu and Kyobashi Community Associations in attendance, to mark Japan hosting the Rugby World Cup in 2019. Mr Johnson is in Japan to lead a trade mission as part of his plans to strengthen cultural ties with Tokyo, with the aim of encouraging investment, job creation and economic growth in London.
