This is the Romaji I could find:
Dynamic Ryukyu
Ikuma Akira with Hirata Daiichi
umi yo inori no umi yo
nami no koe hibiku sora yo
daichi fuminarashi tataku
shima no teeku nu hibiki
umi yo inori no umi yo
nami no koe hibiku sora yo
daichi fuminarashi tataku
shima no teeku nu hibiki
kaze ni fukarete shima wo aruku
yume ni fukarete umi wo wataru
tsuki ni fukarete namida wo nagashi
tsumi ni fukarete asu wo omou
mihatenu yume wa
kanadeteru omoi
toikakeru mirai
hashiru ano sora he
kaze yo hikari no kaze yo
meguru sadame no shirube yo
daichi fukinarashi tataku
shima no teeku nu hibiki
～ kuduchi – rap ～
pai nu kaji fuku
urizun nu gutu ni
muni nu umui yu
katati hanasa na
umi nwatariti
shima nmeguriti
washita niseetaa nu
chimu ya dondon
tisaji meeuchi
uta yu sanshin
haiyasasa ha haiyasasa
haisaisaisa ha haiyasasa
haisaisaisa ha haiyasasa
haiyasasa
haiyasasa
hoshi no kotonoha nami ni ukabete
yozora wo wataru yume no sabani
kuon no sora ni nagareboshi hitotsu
nami wa omoi wo yosete kaesu
na mo naki tami no
koe naki uta wo
michi ni tatsu hito yo
kaze ni toki hanate
sora yo moeru tida no
inochi no ibuki ni yume
ooshiiku hirogeta tsubasa
ten takaku chuu wo mau
umi yo inori no umi yo
nami no koe hibiku sora yo
daichi fuminarashi tataku
shima no teeku nu hibiki
umi yo inori no umi yo
nami no koe hibiku sora yo
daichi fuminarashi tataku
shima no teeku nu hibiki
shima no teeku nu hibiki
shima no teeku nu hibiki
