What you think you'll have an easier time with is what you should do, just make sure you stick with it and practice literally every day while trying to immerse yourself as much as you can. Doesn't mean you'll never see English (or your native language) again, just try limiting your usage of other languages. If you can do it in Japanese, try doing it in Japanese.
