Southern All Stars (サザンオールスターズ) is a Japanese pop rock band formed in 1978. They celebrated their 35th anniversary with their newest single, "東京VICTORY" ("Tokyo Victory"), in light of Japan hosting the Summer Olympics 2020 in Tokyo.
Back in the day in 1940, Japan was supposed to host both the summer and winter olympics (because they used to have them in the same year then). For obvious historical reasons, it was cancelled. Since then, Japan hosted the 1964 Summer Olympics in Tokyo, the 1972 Winter Olympics in Sapporo, and the 1998 Winter Olympics in Nagano.
That's actually quite a few Olympics that one country has had the privilege of hosting. The 2020 Tokyo Olympics is a considerable feat, due to the recent Earthquake and nuclear tragedies in March 2011.
In a recent interview, Southern All Stars was quoted to have said, that "Tokyo Victory" is meant to be a morale boost during these darker times. Japan as a nation still hasn't recovered from the Great Tohoku Earthquake of 2011. The reputation of the country was ruined, with accusations and blames for radioactivity in the Pacific against Japan.
Hopefully the 2020 Olympics will be a safe and wonderful event to remember.
My parents would rock out to this stuff. A little bit of Japanese culture for you.
