I have investigated a lot for this song since it means a lot for me. And well, is all what you all are saying. it's a commemoration addressed to her father. More or less we have the meaning of this...
And yea, her father is dead... tha last song refeared to her father is MA and it's obvious that he is dead:
"Sayonara You have gone to the place where we can never meet again. I can't accept the coldness of the eternal parting" Only is imposible to contact with someone if is dead...
And as someone said here (sorry i don't remeber your name :p) in MA booklet we can see a date written with lipstick in a mirror, is 30th of June. Then if we go back to July 1st lyrics....
"Nagaku nagai sagashi mono wo mitsuketa kibun sa. I feel I have found out what I have been looking for so long"
After so much years she have known sth about her father.
"Ashita ga moshimo Ame datta toshite mo kimi ni ai ni yukou soshite kono uta wo kimi ni ageru. Even if it rains tomorrow I will go to see you And give this song to you"
She is "talking" from 30/06, so "tomorrow" is July 1st, She is making this song for him.
"Ashita haretara Ano umi e yukou kinou nagashita namida no itami wa yasashisa e to. If it's fine tomorrow, I will go to that sea. The pain with the tears shed yesterday are changing into tenderness."
In the documentary in 2004 "light&Shadows" they went to Fukuoka, and when they were next to the pier, Ayu said that:
"I came and sat here fishing with someone. Since I was so little, I don't remember perfectly and I never asked anyone if this is true, but I think it was my dad who I came herd with. I think it was my dad. There was all this fishing stuff in the house and we never got rid of it, maybe he forgot about it." (I take it from the subtitles of the documentary)
So I'm sure this sea she is mentioning in July 1st is that sea where she remember she went with her father. So she wanted to go to Fukuoka on July 1st, to the only place she remember sth about her father to "give" him this song.
So for that reason, if i'm not wrong (and i think not), she knew her father was dead the 30th of June 2002... one month after H was released... This is what i think... XDDD maybe i'm wrong, maybe no...
I don't think her father died in 2003 just before the mini-album and because of that she wrote MA... maybe MA was written in the 1st anniversary of her father's dead, maybe was written during 2002 and until 2003 she didn't decided to record it and because of that is a bonus track...
idk...
what do you think?
