One way we used to save SCADS of money in Japan is to cook 5-6 cups of rice in the cooker and just go from fried rice, to rice balls, to chicken/egg bowl, etc. until the week is over. It saved us $100 equivalent a week.
Used to make gallons of plum wine myself too, and DIDN’T THAT WORK?!
I wonder if My favourite place is still there, just outside the train station in Aki-Habura. 50 Yen for a huge bowl of ramen soup -delicious and you were lucky if you could finish the entire bowl.
Of course, this was back when the exchange rate was 220 Yen to a Dollar. It used to be 110 Yen when I first arrived!
