La Polonia viene nuovamente menzionata nel Golden Kamuy

My friend watches this, and he told me that Bronisław Piłsudski is indirectly mentioned. Makes sense, since he got sent as punishment to Siberia, in detail to Sachalin. He was very connected to Ainu culture, in fact he even had a Ainu family. He recorded lots of their rituals, that have been digitalised by Sony after his death. Really cool to see him being mentioned in foreign media
