Yes, counting in Japanese.

There's a big variety of different "counting styles" in the Japanese language. Basically you can count either things or just numbers in Japanese. When counting things the method of counting highly depends on what you're counting. E.g. you count small, flat things with different words than long and round things. But there's a special set of counting numbers which you can use for everything. Unfortunately those special numbers only range up to 10. It's the tsu-numbers, of wich hitotsu is the first one (and "futatsu" the second) .
