Since it is quite chilly (average day temp 14c) we decided to have nabe or the equivalent of steamboat for lunch. We had some vegetables which are mostly cabbages and leek plus tofu and beef.
The fresh oysters which we bought from a supermarket was good enough for dinner. The oysters (2 dozens) cost about S$7 which is a steal. Oysters are inexpensive in Japan because they are plentiful during the cooler months.
