There are a couple of hotels within easy walking distance of the int'l terminal. However, those hotels were fairly small.
Since it is close to the airport, language shouldn't be a problem but finding it maybe if you aren't up to speed on Japanese.
Last October I had to overnight in Nagoya. I could not find anything at the airport. I took the shuttle bus to the city and stayed at a Days Inn. It was about two blocks from the bus stop ( at another hotel which name I cannot remember). They spoke English at the hotel which was convenient.
