As an English learner, when I learn English or when I talk to foreigners, I feel lost in translation (it is impossible to transfer the whole culture correctly perfectly, something always is lost). After all, there are limits to words, and it is hard to convey to the context that this word after understanding the background deeply is hard to convey.

Today is about the word “Culture” I often use.

Culture (in Japanese)
Sometimes it means human intellectual refinement and spiritual progress and its outcome, in particular products of art and literature, but today it is wider, including the behavioral styles and material aspects shared by members of a society It often refers to a lifestyle. The culture defined in this way consists of languages, thoughts, beliefs, customs, taboos, laws, institutions, tools, techniques, works of art, rituals, rituals and so on.
