I guess we could use the native Japanese numbers, 一つ, 二つ, 三つ...but we'd run into a problem at or after ten (not sure how とお works — same for はたち).
Is there a general counter word that we can fallback on? For example, if something is mechanical I'd probably fallback on 台 (だい), if it's flat 枚 (まい). For more general objects like 11 motorcycle helmets, or 15 packs of cigarettes, or 24 clothes hangers, could I fallback on something?
ge
, which is curiously written (though only in traditional script) 個. :) The difference is that it's far more useful in Mandarin, and it's even the default counter word for many common categories (such as people), while Japanese is a little bit stricter, and if you can use a default counter words for low numbers, you'd usually prefer the native (つ) counters.个
