Hello, I've lived in Japan for about 3 years now and I find these toilets indispensable. For the situation you described, I have experienced the same thing but I have found that there are a few ways of getting around it. The main way is the "move" function, which oscillates the nozzle back and forth. Usually you can activate this by pressing the spray button twice or pressing a dedicated button. You can also usually manually adjust the nozzle position to better suit your needs. Additionally, some of them have dryers which further negates the need for toilet paper. My routine is usually spray, oscillate, check with one or two TP squares, and then dry. This saves me from a lot of hassle and saves a lot of toilet paper. Excuse my vulgarity, but I've had times where what would otherwise turn out to be a "nightmare shit" became a relatively pleasant experience. It's those times where I can really appreciate modern technology. I think Toto did a good job to try to get it to fit the majority of people's needs, but it seems some manual tweaking and button pushing is still necessary sometimes.
