I have worked in Japan for 2 years, but I do not know a lot of Japanese because my old job didn't need it, just a few words of greeting. Where can I find jobs in Japan with this Japanese level?
If you don't speak Japanese, it is not easy to get fancy jobs,
so I recommend to start from jobs like Factory or constructions or maybe Dishwasher at Restaurant.
I'm sure your Japanese will improve, so when you are ready then look for job like Waiter or Hotel Receptionist.
