Sumiyaki Unafuji is a Japanese restaurant in Nagoya that specializes in hitsumabushi, charcoal-grilled eel. It is about a 10-minute walk from JR Tsurumai Station and uses large eel, so the meat is thick and tender, typically eaten with green onions and wasabi. Dinner service starts at 5 p.m., and the shop seats around 30 people, so food comes out slowly because grilling the eel takes time. It is located away from Nagoya's main tourist spots and subway stations.
