Hi Paul! Trying to use Google translate, and my language studies to translate:
Dare Yori Mo Kimi wo Aisu / I Love You More than Anyone
(Man's line)
Dare ni mo iwarezu / Don't Tell anyone
Tagai ni chikatta / We swore to each other
Karisome no koinara / If you love the trifle
Wasure mo shiyo ga / Let's also forget
Aah..yumede wa nai tada hitosuji / Aah...Not a dream, just a wish
Dare yori mo Dare yori mo Kimi wo aisu / More than anyone, more than anyone, I Love You
Woman's line:
Ai shita toki kara Kurushimi ga hajimaru / From the time I loved, the suffering began
Aisareta toki kara Wakare ga matte iru / Since the time of being loved, have waited for the separation
Aah...soredemo nao inochi kakete / Aah...Still when life is over
Dare yori mo Dare yori mo Kimi wo aisu / More than anyone, more than anyone, I Love You
Man and Woman together:
Anata ga nakereba Ikite wa yukenai / Without you I don't live at all
Anata ga arukara Ashita ga iki rareru / Because you are there, tomorrow I can live
Aah... iku saigetsu kawaru koto naku / As time goes on, without change
Dare yori mo Dare yori mo Kimi wo aisu / More than anyone, more than anyone, I Love You
