Is this really what they use as Barbeque Sauce in Japan?

My spouse and I been trying a few recipes from other cuisine from time to time, but I recently stumbled upon some brand that claims it is Japanese BBQ sauce. ( Bachan's ) and it not bad as all BBQ sauces I had are tomato based instead of Soy based. But I have to ask, is this really what they use as BBQ sauce in that country?

I seen a few condiments and recipes say its, "(insert country here)-style" and that is not what they used there. So I figured I ask.
