"Shoyu" is still the correct word in Japanese for referring in general to soy sauce (rather than to particular types of soy sauce, for example, tamari, shiro, or koikuchi).
"Shoyu" weli waa eraygii saxda ahaa ee Jabbaan ee loogu talagalay guud ahaan ulaha suugada soy (halkii laga oran lahaa noocyo gaar ah oo maraqa soy ah, tusaale ahaan, tamari, shiro, ama koikuchi).
