I really like the vibe around Nagoya. At every corner you see another artist (singer, band, dancer) practising what he or she loves to do.
One lovely memory about my trips to Japan was for sure that warm evening in Sakae when I walked around a park and a band played some really good songs. I stopped for a while listening to them and watching the passing cars and lovely lights all around me.
From the TV tower you will have a nice view over this area. I've went up when it was dark already and I think that's the best time to go up, or maybe just before sunset.
Around here you can try out the famous Miso Katsu (pork cutlet served with thick miso sauce). The red miso is really strong, so maybe it's not for everyone, but I love it!
