I Imagine if you're looking at this hotel, it is mainly that you are on a business trip there. This city is famous as Subaru city.
The actual name of the hotel is Toyoko-inn Gunma Ota-eki Minami-guchi.
Staff: They don't speak english so try to have Japanese friend with you to assist you.
Rooms: Are small but amazing since you can find whatever you need in this smart designed room. You can check the pictures. : Slippers, Hair Dryer, A/C ( in Japanese but you can manage), Fridge, Desk, ....
Hotel is clean as everything else in Japan.
I didn't have breakfast in the hotel and I was surprised to see so many persons having Japanese breakfast very early in the morning , 6. 10 am.
I will come back to this hotel in case i need to stay at Gunma. Anyway, other hotels in the city would be of quite same level ( I don't think you can find higher...)
