you are just idiot japan can do everything in japanese better than any other country in the world, so there is no need to rely on languages other than japanese, so there is no need to bother learning english or other languages languages other then japanese can only express meaning, but japanese can add emotion to meaning, such as particles and exclamations, and can construct relationships other than meaning, such as casual and honorific expressions, making japanese the only language in the world that can maintain peace through free will without being bound by ideology or ideology also it is the only language that can express science and the embodiment of thought better than any other language, so it is a language that can express intellectual and emotional expression to a much greater degree japanese > english
Japan
