Japanese Banner Opinions Please

[Wade]

I found this banner today. It is 2' by 6' with edge tab loops for hanging. I would like to know if this is a genuine item and what the writing translates to please.

I think it might be beach related, non military.

I do not think this is ww2 related. Anyway,
1.harbor
2.built
( 1 and 2 to be read together and it may be the name of that place where this banner is placed before)
3.thousand
4.bird
5.island
( 3, 4 and 5 to be read together to form the name of the place)
6.sea
7.water
8.bath
(6,7 and 8 to be read together)

Thousand+Bird+Island kanji = "Chidorigaura"
Chidorigaura Ocean Water Spa
It's a 100% genuine advertising banner, 0% military
