If you are a bargain shopper, you might like to consider going to Saturday's flea market. There are various flea markets and yardsales.
You can find items like potteries, clothes, antique items, jewelries, etc.
What to buy: I bought a antique silk table cloth for about $24.00. It was a good deal!
What to pay: You can bargain and tell to the seller how much you can afford to pay.
The first time I went to Ibaraki, I thought those pushcarts found at the grocery stores are so tiny! (I was comparing them to the huge grocery pushcarts we have in the United States). Little did I know after buying some food that the cost of food in Japan are super expensive! They just have to have small grocery pushcarts as to fill a pushcart will cost you thousands of dollars!
The grocery store in Ibaraki is called Jusco. Not sure why. It sounds more American than Japanese. Maybe, the owner have a link with Costco? The parking of the grocery store is very nice because there is a covered walkway that connects it to the grocery store. This is a safety element of the store which is very nice. When it rains, you don't really get wet going back to your car.
The store entrance has some mini-stores that sell take-out food.
The grocery itself is very clean and orderly. The fresh and vegetable section is neatly arranged and most of the vegetables are packed and tagged nicely.
Most of the products Jusco is selling are all made and produced in Japan. There are no translations or whatsoever on any of the products!
What to buy: Grocery items and fresh fruits and vegetables.
What to pay: Depends on what you buy

What to buy: I bought some Japanese curtains
