Not all native people can teach their own language to learners as the template for profiles on this site describes.
I know it's hard to teach languages, so I learn how to teach Japanese language to foreigners.
So I don't want them to say "I can teach you" to me easily.
Besides my job, I teach Japanese language on Discord for free as a certified teacher. That's my hobby and voluntary work.
If you're interested in my class, please feel free to contact me, however I don't tell unknown people my accounts like Skype, Line, Facebook, and so forth (except for Discord). I don't need language exchange in English, but am willing to help people with Japanese.
