Can an Indian get a teaching job in Japan?

I'm a student from India. I am fluent in English and in my native language which is Hindi. I know conversational Japanese and I plan to get fluent at it till mid-2019. I also plan on learning Spanish and French which will make me a polyglot. I'm going to get a bachelor's degree in English and also a tefl after I finish school and will teach English by the side , giving me 3 years of experience in both online and offline teaching. I don't have any issues with accents I can speak in both British and American accent.
Will all this be enough for me to get an English teaching job in Japan? And if not ,what qualifications will help me become highly employable despite of being a non native speaker?
Sorry for the long question 😅

If you are a non-native speaker of the English language, if you apply for a position looking for native speakers, you will need to have 8 or 12 years (forgot the exact number) of education "in" English (meaning educated "in" the English language, not studying the English language as a subject) to show that you are equivalent to one.

You say you will have a bachelor's degree (this doesn't have to be language related by the way), so that part is no problem. (It is "either" a bachelor's degree OR 3 or more years of language teaching experience that is required).

It will be a matter of finding an employer who is interested in your background and is willing to hire & sponsor you when you actually come to Japan. So the demand for teachers at the time when you are ready will play a role. Just one thing to note is that you will be competing against native speakers of English for teaching positions.

The two Indian schools that I know of are:
India International School in Japan
Global Indian International School

Both have websites. Maybe you could contact these schools through their websites and ask your questions to them.

Good Luck.

With these qualifications do I have a chance of getting a job in gaba,kids duo or other recruitment agencies which don't require native English speakers.

Yes, I believe you have a chance. Just please note that it also depends on the competition/demand at the time.

There are 2 things here. A company that would offer you Job and company that will offer job and also sponsor visa and do all paperwork for you

First one is easier to get and you will already in Japan if your visa is in place

Second one is difficult and usually happens while you are in India.

Are there some qualifications which can increase my chances of getting hired?

Would it help if I can teach a certain subject along with English (like social studies or history)?
