Curry arrived from Britain, not India カレーライス
The curry manufacturers’ association tells its own trade’s story: in early Meiji, British curry powder arrived with the British method and met rice as “rice curry”. What made it national was the military — the association credits adoption into mess menus as the trigger, with discharged soldiers carrying it home to every prefecture. Its roots are Indian; its route here was the Royal Navy’s.
