It's been a while since I learned Japanese. When I read this thread, my first thought was "Of course I can!" and began to count, only to realise I'd forgotten the word for 'five'. So... Close enough?
It’s been done plenty of times in here so I’m not gonna repeat it, but I also learned it from karate. Learned to count to 20 there xD When watching anime I realized that there’s different pronounciations for some, so yeah that’s one of the few things I know in japanese.
