It was fine and hot.
Today is doyo no ushi no hi (土用の丑の日), the day of ox during the dog days. On this day there is a custom to eat eel. Eel is unagi (鰻). We usually eat it as either unadon (鰻丼) or unaju (鰻重). Unadon means unagi (鰻) and donburi (丼), eel and bowl. It is a rice bowl topped with grilled eel with sweetened soy-based sauce. Unajyu is set in a tiered food box called jyubako (重箱). Both tastes are the same but different in style. Unajyu may look more sophisticated and expensive.
The history of eating eel on that day started in the early 19th century.
