Japanese expends a lot more syllables to say the same thing that English can say in fewer. Even more if you use the polite form (e.g., speaking in a business context, train announcements, etc.) Grandparent post was not the first person I've observed to notice this.

Japanese syllables are often shorter than English syllables, and a native speaker can articulate then quickly and fluently, but it seems to take much more linguistic "mass" to say a thing in Japanese compared to its English equivalent, unless you use a blunt direct form.
