How to be a teacher in Japan?

Hey I have 20yo, I have a bachelor degree in English studies ,I live in Casablanca , I have a good level of English , also I can speak Arabic fluently because I live in an Arabic speaking country, I want to try the experience of teaching Arabic or English in Japan ,and learn about the Japanese culture and also meet Japanese people.

Generally speaking, most companies in Japan look for native or at least near-native level speakers of English if they're going to be teaching English. I'm not trying to be rude, but looking at the grammar that you're using, It's all over the place. If you really want to teach English, you would have to prove to the company that you can speak, understand and write very well in English, since it's literally the language that you're trying to teach others.

I'm not saying it's impossible with your skill level, since I don't really know how well you speak it. I'm just concerned from what I saw what you wrote and how the English ability seems to be far off. I'm not perfect myself, but you'd definitely have to demonstrate your ability to a company, especially considering there are many native speakers who apply every year for teaching jobs.

I wish you good luck either way and the best thing to do is literally just apply and see what they say. Most companies want people who will want to stay in Japan for a long time and not just to teach for a year or less since the hiring process takes a long time.

you want to be a 'Language Teacher' .. first you need to check whether you eligible for 'teaching' work visa.

As a native English speaker I have to agree with Al that your proficiency level is not high enough to be teaching it. I have no problem understanding what you are trying to convey and in that sense your English is quite good, but for example a native English speaker would have said this:

Hello I am a 20 year old from Casablanca with a bachelor degree in English studies (In English when referring to age we never use the verb 'have' age is not something possessed it is something you are). I speak English proficiently and can also speak Arab fluently. (noting that you live in a country that speaks Arabic is redundant because you already mentioned you live in Casablanca) I would like to either teach Arabic or English in Japan. ("I want to try the experience of teaching" is just altogether bad grammar and 'wordy') I would like to use the experience of working and teaching in Japan to learn about Japanese culture and to meet Japanese people.

Sorry to be nitpicking. As I said your English is of a fairly decent level, but not what I would expect of someone teaching the language. I think your talent is probably better suited to being an interpreter although I don't know if there would be opportunities to be an English - Arabic interpreter in Japan, but perhaps you could find opportunities in the US, UK, Australia, New Zealand etc. Or if you want to experience Asian culture perhaps in Indonesia? Perhaps there are some opportunities to teach Arabic in Japan, but I would imagine they are limited or only at collegiate level.
