How do you say ~ ? (in Japanese)

How do you say "I'm sorry?" I think that in most circumstances, it is best said as, "sumimasen" (すみません) and not "gomen-nasai" (ごめんなさい). Occasionally, when you actually mean to apologize for something you've really done wrong, it is appropriate to say, "sumimasen moushiwakenai-desu" (すみません　申し訳ないです). "Gomen-nasai" sounds, to me, rather intimate, like the kind of thing that is said between parent-child or spouses.

Do you guys say You're welcome in Japanese? It's hardly ever used, but I feel awkward after having someone say Thank you to me.

Recently learned how to say "educate oneself" in Japanese: 教養を高める kyōyō o takameru

Literally means "raise one's cultural level".

My mother language is French and it's an expression I'd use often but Id never encountered it in Japanese so far.... I really need to study more 😅

Sometimes I struggle to express some NA/European (?) concepts related to spirituality, lifestyle or society issues. And I'm surprised when a katakana word from English is then used. Example: wellness. I've seen it a lot of times on insta like this: ウェルネス. Sadly switching to katakanazed English doesn't work every time 😂😂

To say lottery in Japanese is 宝くじ　(Takarakuj)

To say for a moment or an instant in Japanese is 　一瞬(Isshun)

I often hear this Japanese word 万引き　(MANBIKI) which means shoplifter or shoplifting. AVOID DOING THIS!😀
