Learning japanese to enter in a music academy

I'm a Malaysian with native language of Chinese.
I also know English and Malay language.

In my opinion, it isn't impossible to master Japanese in one year provided that you're living in Japan and speaking only Japanese most of the time.
The harder part for JLPT certification is actually learning all the Kanjis.

If you have base knowledge of Kanji such as coming from Chinese background, you can definitely complete N1 in a year.
Assuming you're Belgian, you might find that it's hard when it comes to Kanji but immersion is all it takes to learn more Kanji.
With that said, if you're taking the Japanese course in Japan, it shouldn't be too hard to reach N2 within a year.

Good luck and have fun while studying Japanese. It's what keep you going.

Sorry, I feel it is not possible to get n1 level in 1 year.  N1 is almost fluent.  I am n3 level in 2 years Living in Japan and working for japanese company. Main language is japanese. Maybe full time japanese lessons would get me to n2 in 2 years. But still... Ganbatte ne!

I agree with you.
Actually I will not be going soon to Tokyo. I think I will go there in August or september.
That means I have 6  months to get a method learn japanese bases at home.
When I will go to Tokyo, I will spend 20h/week in a japanese school during 10 or 11 months.

My objective is the N2 level.

Maybe yes, but still...

You could of course mainly focus on passing the test. That is a little bit a different focus than really speaking understanding Japanese.

I focussed on talking and listening. Not so much on reading. For the test reading is much more important, so quick start on learning kanji is usefull. This might give you a chance to pass the test.
I also heard from colleagues that many chinese pass the test mainly because they can read kanji.

Next to language school using the books Minna no nihongo,I use the app duolingo, a fun way to keep learning and work on my reading skills.
There is only japanese to english available at the moment, but it works just as well as the other way around.
