Taxation on capital gain on stocks held abroad

Hello,

I hold some foreign stocks with a broker domiciled in my country (not US but European Union country).
If I sell foreign stocks held there and realize a capital gain is it tax in Japan as a comprehensive income (総合課税) at my marginal income tax rate or separate income (分離課税) 20%.
I have a permanent resident visa in Japan.

Thanks
