I would take number Two but I would remove fish and rotate red circle lower and make that bit smaller.
The mountains aren't stylized enough for Japanese tendencies. Ravenflight is correct, though I think there is a compromise here somewhere.
All seem to agree the fish are a bit much, but I also find the Bear a too European/Western idea on a map. I don't pretend to know much, though, in that regard.
However, keeping the blue sea, white land, and red sun, throw in a current use stylized mountain range and I think you've got it. Though it does look a tad like preschooler tepees.
Just my view, and it could be totally wrong, but it doesn't look like the kind of flag the Japanese would design.
What period is the Japanese that designed this flag?
So, something... roughly like this, then?

I like this with a white ring around the red sun. A bit thicker than the one from the first Alt-Suggestion.
And best of luck with your TL!
For reference, here's a list of national, prefecture and municipal flags. Almost all of them have simple geometric designs, usually centered and bicolor. None of them have animals.
How about just the sun disk in the centre, like the Japanese flag, with the dark-blue background?
