Thanks for the correction!

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.
