My Japanese isn't fully fluent, but I can read the first subtitle at 0:30 (the others are blurry and in alphabets I can't completely understand). It doesn't say anything particularly useful:
"We Will Rock You English rock band Queen's 1977 hit. 'Don-don-cha' rhythm beat."
"We Will Rock You
English rock band Queen's 1977 hit. 'Don-don-cha' rhythm beat."
