I recommend using Google Chrome when viewing these pages, because they're in Japanese and Chrome has the ability to translate most of it for you. To watch the opening videos, just click the video there and it should play.
Or, you could go on Youtube and type in the name of the game and 'opening movie' (Ex: Heart no Kuni no Alice opening movie) and you should get the results.
