On the other hand, there were cases in which station names were distinguished through means of adding company names or some other words; in the case of Joshu Dentetsu in Gunma, 'Joshu' is added to Tomioka Station and the station name is made to 'Joshu Tomioka Station'; the reason for this naming lied in that if the provincial name of 'Kozuke' is added, there is a possibility of being confused with 'Ueno' (Taito-ward in Tokyo) or 'Ueno' of Ueno City; Japanese National Railways and East Japan Railway Company used neither 'Kozuke' nor 'Joshu,' following the examples cited above and made a new station name by adding the current prefecture name Gunma.
一方、社名やその他の語を付けて区別することもあり、群馬県の上信電鉄では旧国名の「上野（こうずけ）」を冠した場合に上野(台東区)や上野市の「上野（うえの）」と混同する恐れがあるため上州富岡駅のように「上州」を冠しているが、旧国鉄及び東日本旅客鉄道では前述の例に倣って「上野」と「上州」のいずれも用いず群馬藤岡駅のように現在の県名を冠する駅名を付けている。
