It sounds a bit weird to me too but that's how it says in the original text. Literally it says "It looks like I don't visit here very often." Sounds strange in English but it's quite normal in Finnish (in spoken language as this one is).
"I don't usually visit here" sounds good to me but the meaning isn't exactly the same as originally. You can change it if you want. I wouldn't do it because the meaning wouldn't be the same anymore. It's up to you!
