SMAP's Masahiro Nakai has once again been selected by TBS to serve as the main caster for its Olympics coverage, making it his third consecutive appointment to that role. Along with that comes the announcement that SMAP will be singing the theme song, titled "Kono Toki, Kitto Yume Janai." Written and composed by Hi-Fi CAMP, the song will be SMAP's 43rd single.

"Kono Toki" goes on sale August 13, the same day that Japan's baseball team faces Cuba in the opening match of the Olympics. Cuba ended up winning the gold medal in 2004, while Japan took home the bronze.
