In Nagoya miso tonkatsu is called “misokatsu” and as
armagebedar suggested
Yabaton takes the claim as the original misokatsu. The first one to come up with the concept of miso tonkatsu.
In Nagoya Marriott, Hilton, and Westin are considered to be a top end hotels. OP wrote on the title “Mid-range” so I got the impression OP was not looking for a hotel like Marriott, but looking for something simpler, smaller, and cheaper. But sounds like OP is happy with Marriott, then OP will be looking at high end hotels at Nagoya.
I just wanted to add. I do not know what kind of dinner you are looking at Nagoya, but misokatsu (miso tonkatsu) is no way considered as high end meal. Wanted to add because if you are at Nagoya for business and want to treat your clients for some nice dinner then I would not consider misokatsu as an option.
