It's the same in Japanese. In Polish the counting system is pretty...normal, I think? Depends on what you consider normal. But just like with everything in Polish, there's a lot of declination and different grammar forms. So, for example, when I count, it goes: jeden, dwa, trzy, cztery, pięć, sześć, siedem, osiem, dziewięć, dziesięć... and so on. But when I want to say: "Ala has one apple" it wouldn't be "Ala ma jeden jabłko", it has to be "Ala ma jedno jabłko".
