SWEET WATER (amai mizu)
music&lyrics: yumi nakashima / translation: hana

outside is overcast, inside is light
if you're happy, isn't that nice?
a spider with its threads, a tiger with its fangs
don't fear of causing harm

our palms touch
from that warmth
those sweet hands
will end without dirtying others'

if the enemy is someone, if dreams are demons
if you can't see even what's ahead
and it's a helpless battle
won't you back down?

our palms touch
from that warmth
those sweet eyes
will end without wetting others'

our palms touch
from that warmth
those sweet hands
will end without dirtying others'

though your dirty, 
abusive language annoys me
I won't dirty
these hands and you and tomorrow


Comments:
There's a song Japanese children sing to call fireflies to them, and it goes something like:
"come, fireflies
the water here is sweet
the water there is bitter"
This is where I'm guessing the title came from.
