^ It was a restaurant/beach house that was also used for filming of Ayu ready?, which opened from the beginning of July until the end of August in 2003.
This site has a kind of brief photo history of it if you're interested:

Just click on the dates and you can see the building through taking down of the beach house.
You can also see some pictures from Ready Go! Sept. 2003 issue:

And, the top of this page are the screenshots for the Greatful days performance she did there:

Someone mentioned she sang HANABI ~episode II~ there as well, but I couldn't find anything about it?
I think she may have sang more songs, but only aired that one. Otherwise, I feel like they wouldn't advertise as much as they are? But who knows haha.
She should have done it again! That would have been really cool. Even if she doesn't have ayu ready? anymore, she could have probably teamed up with some sort of beach bar in Enoshima

Would have been good promotion too without her actually being present. Such potential wasted haha.
