I'm unsure how relevant my experience is as someone who has learned (some) 日本語 as a second language, but I find that I do not have any more trouble typing in Japanese on the keyboard than I do English. The IME in Windows and OSX is quite good at determining which kanji makes sense in context. In that case, it's as simple as pressing space/escape/enter to confirm the selection. I've always remapped capslock to escape because I'm a vi user, so I tend to gravitate towards that, but there's definitely choice there. I do find the flick method to be significantly faster on a touchscreen, however, I'm still quicker with a regular qwerty keyboard. I'm curious if we would see similar results if swype-style keyboards had as much domination among young people in countries that use Roman characters as the flick method does in Japan.
