Can you enjoy online shopping in Japan? There a lot of online shopping site in Japan. We,Japanese buy everything in these stores at very cheap price.And as you know,It's very convenient for busy persons because the items bought by online shop users are delivered to customers home in one or two days.
However I don't think you can do it.Because most of Japanese online retailers doesn't have website in English.So it's difficult for foreigners to enjoy online shopping in Japan.
You may have to buy everything at higher price in retail shop.
