Japanese is, for the most part, not more expressive than English, it's differently expressive. Same for every other language. The bit rate you mention is mostly a limitation of how quickly speakers can speak and listeners can listen. The cohort of listeners and speakers mutually agree on how to bucket the spectrum of experiences into a finite number of words, but different cohorts can bucket experiences differently. In practice this means there's a lot of English words that get smushed together in Japanese[0], and a lot of Japanese words that get smushed together in English[1]. Japan also has a lot of shared cultural experience that Americans or Brits won't recognize, and vice versa, which translators have to spend time explaining.
