Did a Japanese person tell you that?
They occasionally roll their tongues, especially when drunk and want to sound cool like the yakuza
I personally roll my Japanese R's often when it's combined with 'i'
so when I say arigatou, you'll hear a roll out of me most likely.
I asked a Japanese before how close my Japanese R's are and he said he couldn't distinguish mine from a native, but he could have been full of it.
I learned how to roll my tongue through Japanese. The fact that you are rolling tells me you're doing it right. Just don't roll it more than once like in Spanish. You can try and cut the rolls out, I don't think you need to revolutionize how you say R because it sounds like you're getting the hang of it already, you just need maybe a minor change if at all
I'm not a native though, so take it for what it's worth..
