How to buy japanese sauce

This is how I buy sauce here in Japan whether it's a teriyaki sauce, soy sauce, tempura sauce, udon sauce, ramen sauce or even just a seasoning sauce. I just sometimes watch this small monitor hanging on the shelf and trying to figure out on how to use this particular sauce. That's how hard it is to read japanese writings, I hate it. I think I need to start learning katakana just to help me out on buying food off base. But another problem is, Japanese not only has katakana but they still have hiragana and the worst is kanji, my daughter said it's hard to read kanji coz it has 2000+ characters....ohhh never mind then, I think I'm stuck here with this monitor ha ha ha.
