I originally didn't have that "Please stop here!" in German, only realized that very recently. I actually contemplated whether or not to change that for quite a bit, since I didn't have the space to put the "translation" in that I have planned for later. But I eventually figured that it probably wouldn't make sense like that (even if they'd be lucky to get a taxi driver that knows Japanese).
So, too bad for those not knowing German and not reading these notes. ;)
