In France, it is a compulsory subject.

"Compulsory" isn't used as much in American English in this context as "required".

In my view, French is hard as a language for me because my dyslexia ismakes it difficult to control, do the differenctiate between “b” “d” “p” and “q” in words or sentences.

You could also say "makes it difficult to tell the difference between"

BuildForming the words correctly is a real challenge.

Weirdly, "word building" is a phrase in English, but we never say that we "build words". It more describes using prefixes and suffixes to create and change words.
Instead I have suggested "forming" as it could refer to written or spoken language, for writing you could use "spelling" or speaking you could say "pronouncing".

Reading a text maycan be an emotional experience.

Avoiding repetition here as "may" also appears in the next sentence.

But THowever, this difference makes the language beautiful.

Avoid starting a sentence with "but" as it is a connector. Another suitable option is "Nevertheless"

It ownhas a rich vocabulary.

"Vocab" is informal, best used in spoken conversations or texts.

The specific sentence may be amazing.

I am not sure what you are trying to say here.

I have been learning this language since the 6th grade (?)

Present perfect continuous - you began in the past and continue today

If you're not sure of the year, you could just say "since middle school"

I began studying Japanese in January 2017. t The first video who I watched to learn Japanese was “Japon fou fou fou”.

"who" is for people

I started studying this language because I still found this languagefound it very beautiful.

TheIt sound is very calm, I and I can distinguish all the sounds without difficulty.

When I began to learn about their culture, it became evident to me that I wanted to speak Japanese, I wanted to visit the place.

"When" here is a subordinate clause, and you need the main clause to complete the sentence "it became..."
All the sentence took place in the past, so the verbs must all be in the past too.
"want TO" + verb
However, "visit" is not followed by "to"

It becomes evident to me, I want to speak Japanese, I want visit to a place.

I want moreto known more.

I love Japan Feodal, it's myfeudal Japan, it's my favourite period fav.

The Sengoku period is good because this is the period when Japan birthedwas born.

A mother BIRTHS a child.
A child IS BORN.

Oda Nobunaga succeeded in unifiedying the country.

After tTheir religion, is Shintoist.

The divinityIts beliefs and story are amazing!

"Divinity" is used to describe a specific God .

I believhope to live in Japan one day, even though Japan has a dark period e.g., for example

Good use of idioms!

Come on guys, make me want to learn a culture.!

I was born andin and still live in France.

"I was born," generally requires the use of "in" to specify location. Otherwise it just means "I was born". "Born in France" implies that you lived there at that specific instance and time, "still" should be used with actions that you have done in the past and still continue to do.

In my view, French is as hard as a language for me because my dyslexia is difficult to control, dolike the differences between “b” “d” “p” and “q” in words or sentences.

"as" used before the adjective it means equal in comparison to. I think you meant "like" or "for example" in the last part, to give examples. Difference is plural because there are multiple differences between those letters

BuildPlacing the words correctly is a real challenge.

I think here you might have meant the placement of words in a sentence. Or structuring, "building" is more often than not used in a literal, physical sense.

BuYet Tthis difference makes the language beautiful.

"But" is more so used with two phrases. It could be used to connect this sentence to the previous one, to contrast.

It ownhas a rich vocab.

"Own" is usually used more in a direct way, for people in general.

TheAny specific sentence maycould be amazing.

"The" means a singular, specific sentence. Any means all which I think you were trying to do here. Could is used more than may
for a potential to be.

- English ¶

I¶
¶
I have learned this language since 6th grade (?)

"I learn" is in the present, "indicative" tense. I have learned means that you have had that experience since the past, so the past tense -ed.

ofin middle school.

"In" indicates a place, "of" indicates ownership

In France it is a compulsory subject.

"it" (the English class) is the compulsory subject, not France

I don’t have any skills in the language.

"Any" here is used to generalize the meaning of skills.

I began Japanese in January 2017. the first video whothat I watched to learn Japanese was “Japon fou fou fou”.

"Who" means identity, i.e. a person. "That" can be omitted, it just refers to the video.

TheIt's sound is very calm, I can distinguish all soundsthem without difficulty.

The sound belongs to it (Japanese language) so it has an 's for possession. Using "all sounds" again is redundant

When I began to learn about their culture.,

This sentence is a dependent clause, it relies on the next sentence.

It becoames evident to me, that I want to speak Japanese, I want to visit to ahe place.

Became, past tense. "That" connects the two otherwise independent clauses. "I want to" comes before the verb, and "the" referring to Japan,
"a place" means any place on the Earth in general.

I want moreto known more.

If "more" is used with a verb it must come after. If it is used with a noun it comes before. I.e. "I want more knowledge."

I love Japan Feodal, it's myfeudal Japan, it's my favorite time period fav.

Adjectives are not capitalized, and always come before the noun. "time period" specifies what type of "period".

The Sengoku period is good because in this period Japan birthedwas born.

"Birthed" is generally used only in a biological sense, otherwise in the past tense it's born. "In" for things within.

Oda Nobunaga succeeded in unifiedying the country.

After tTheir religion, Shintoist.m,

Dependent clause combined with the next sentence, a "Shintoist" means a follower of Shintoism.

It is polytheistic.

Their divinity and story are amazing!

I believewant to live in Japan one day, even though Japan has a dark period e.gtc.

"Want" to express desire. After using "e.g." you must give one or more examples. Use "etc." instead to mean
"and so on".

In 1880-1945 the Japanese Empire colonized Korea and China.

Empires as names are generally used after adjectives, like "British Empire", and they have to have
a definite article "the".

But I live perhaps not definitivelyI don't live like them because I am unlike their actual politics but I continue to study their politics, cultures, religions, and the remainderetc.

I believe that was what you were trying to say in the first part.

cCurrently, my level isI am at a beginner level, I think.

SincereReally, I don’t know.

Sincerely is generally formal and used at the ends of letters.

I directly began to read a text in simplified Chinese (The text had to be written by a Piekinese because there was a lot of “儿” and my friend said to me “It’s a Pekinese” with Pinyin.

PrioritMainly, I study Mandarin (in simplified) but I don't mind learning traditional and Taiwanese too.

Priority is used to express first in a series of concerns, in general.

I believe in the day when can I speak in their language without speaking English or French speaking.

For the culture of the country (China and Taiwan), I haven't studied yet because I'm going tod be spreading myself too thin, so I'll just be learning things left and right.
