After seeing off a client/friend at the airport, Inogashira-san passes through the Keihin Industrial Zone. Before embarking on a long drive back home, he stops and idly watches the view of steel infrastructure frameworks of the zone's steel mills and oil refineries from a distance. He is hypnotized and impressed by their immense size, towering smokestacks and complex design. And yet, it also somehow, reminds him of... well, food, most particularly, yakiniku. He goes in search of a yakiniku eatery in Hatcho-nawate, Kawasaki and settles for "Tsuruya" which offers solitary dining for individual customers. It's perfect for a ravenous lone wolf like Inogashira-san!
