しんじゅく (Cиндзюку, Sindzyuku) is an interesting case, as it has both し and じゅ in it. This is where Polivanov is similar to Kunrei. OTOH, Fukushima is cyrillized as Фукусима (Fukusima), where the ふ is a fu in Hepburn, hu in Kunrei and fu in Polivanov but し is not shi as in Hepburn, but si as in Kunrei.
Transcription gets even messier when more than two languages are involved. Russian uses the Polianov system as a "cyrillization" method. It's neither Hepburn nor Kunrei-shiki, which can be confusing if you are a Russian Language learner and know Japanese or English.
Some Japanese words entered Russian not directly, but through English. In these cases, the word is first romanized using Hepburn, and then adapted to Russian using English-to-Russian rules. A classic example is 寿司, which Polianov would render as суси (susi), but Russians mostly know as суши (sushi). Then there are words which actually do faithfully follow Polianov, as in 新宿, which is written as Синдзуку (Sindzuku) instead of Шинджуку (Shinjuku).
Unfortunately, this is not just a problem limited to Berlin :-( [1][2]
It's been an absolute mess trying to secure my wife's settlement permit ("Niederlassungserlaubnis"). She has a german Master's degree, works in a government-funded research facility, and has been in the system since December 2022. We've now been ghosted for 14 months, only to be told to make an appointment to provide additional documents (which were not on the 'required documents' list they initially handed to us). After checking the appointment booking website to no avail, I came up with a python script that sends a notification to our phones when a new appointment pops up. It took 40 days of scraping until a new free appointment was available, only to be allowed to provide paper documents in person.
Adding to that, every six months, her employer threatens to fire her if she can't prove her legal status in Germany. So she's constantly jumping through hoops to get this temporary paper permit called "Fiktionsbescheinigung" just to keep her job. It's a hassle, costs €13 each time, and involves cycling through multiple unhelpful bureaucrats at the Ausländerbehörde's hotline (they do not answer emails) until finding one that very reluctantly produces this document.
Poor UX for medical systems is something that has always baffled me. I used to work for one of the major CT system manufacturers (although on the firmware end of things). I never understood why a hospital would willingly pay a seven figures price tag for a medical imaging system that comes with an early 90s GUI.
Ultimately, it is not the radiologists or technologists who make this decision. From a purely technical point of view, modern systems hardly differ from each other, at least as far as diagnosis is concerned. The fact that a better UX means new users need less training and the time between scan and diagnosis is reduced are hardly taken into account when making a purchase decision.
