Are AEON curtains in Chiba, Japan duty-free?

It's not tax-free. Located in Zhang Mu, Chiba Prefecture, "Wang Yongmeng visited Zhang Mu New Capital" (ィォンモールル Zhang Mu New Capital) is a large shopping center integrating shopping, entertainment and food. Not only the shopping brands are complete, there are many food choices, but also it is very convenient to start from Tokyo! Both adults and children can have a happy day here!
