Due to environmental concerns, a nationwide charge for plastic shopping bags began on July 1st this year. Many people have likely experienced the situation at checkout: "Oh...it won't all fit in this bag. I guess I'll have to buy a plastic bag today..." From now on, it's a good idea to make it a habit to always carry your own reusable bag when going out, so you can manage to some extent no matter when you go shopping.

Here are 12 highly functional and stylish bags that can be used as shopping bags or secondary bags, available at Isetan Shinjuku Store, Men's Building and the Mitsukoshi Isetan online store.

This fashionable portable bag easily transforms from a tote bag by simply pulling the handles. It's also washable, making it convenient to clean at home.
