The grounds are lined with a bunch of tents, and piles of affordable Kutani-Yaki wares are displayed. That's just overwhelming! Under the tents, people freely walk over their checks. So don't hesitate to walk in! Just be careful with those fragile articles! Carrying backpack might not be proper for the market as you guess!
As soon as you start checking at a stall, many articles of trade will be sold like cakes! Let's bargain over the prices! If you want something very Kutani, I recommend you to learn about the porcelain before getting there. At the open market, you will probably see both cheap and expensive in the same line, and might wonder why. Check the patterns to compare the qualities! So you can see how masterpiece's is beautiful. However, cheaper ones are also Kutani-Yaki, and not defective products at all. You'll find something good within your budget!
