1st part of the letter:

Recently, Hamasaki and I have been eating together.
It was at Roppongi's "MAKKUROO".
"Why here??" you ask.
Well if we ate there, Ayumi's friend MIKAJON (PEACHJON's president) would meet us, and he said he would give Ayumi some information.
So, the theme was not special.
Sometimes it's just the two of us. It's normal and we talk about various things. I wonder how it will be later this year. Actually, if we are able to make fairly good singles, there might be an album by the end of the year. If that's the case, there'd soon be a tour but I don't really want to talk about these possibilities.
Now that I think of it, in 10 years Ayumi will be like Madonna or Yumin (?) but not just anyone.
In today's Japan, to have young fans still support a female artist while in her mid-30's would be a first.
No doubt about that. (in other words, he thinks Ayumi's fanbase will hold strong for the next 10 years)

[there were some words I wasn't sure of, correct me if I made mistakes. Especially with the names]
