I am strongly against having a World Cup in Japan for many reasons.
1st is the safety of players. Because of the meltdown of a nuclear power plant, the level of radioactivity is at a dangerous level, including Tokyo.
2nd is the anti-sporting attitude of the Japanese and government and Tokyo Metropolitan authorities. The former Governor of Tokyo, Ishihara Sintaro, is an open racist and historical revisionist. Do you know the racist repressions on Koreans and Korean Schools in Japan?
3rd is the lack of decent stadium. The National Olympic Stadium has been a national stadium of Football. It was built for the Tokyo Olympics in 1964. Despite there are enough number of decent athletics stadiums in Japan, the re-innovation of the National Olympic Stadium is building athletics stadium again. The reason is the Olympic mania of the racist Governor Ishihara.
