Japan has many variety of grapes, so many that we haven't tried all of them.
Recently the little fruit/vegetable stand that I often visit had these Golden Niagara grapes...2 bunches for 298 yen plus tax.
Since we'd never tried them, I picked some up.
They have a musty green-yellow color and the fragrance is super sweet.
But, they have TONS of seeds and the "skins" are quite bitter.
Oh well, at least we got to try these.
