Yes, I only attempted as I'm confident in four languages and learning more

To be a translator, you need to have at least two years of a foreign language or have the language learned naturally, usually by birth. I appreciate your knowledge of Japanese, but right now, we do not have a dovahzul/japanese dictionary. Hopefully sometime in the future, we will, but right now, sadly no.

And it would be best if you weren't still learning the language. I only applied for the job after I finished learning French, at least to a degree of basic fluency.
