Don Quijote Korakuen

I wouldn’t exactly call this a discount store, but the prices are very good on every from fresh food to perishables to beauty products to kitchen appliances to bikes! This place is really a minefield for your wallet; you will always find something you need to get. Alcohol? Drinking snacks? Sex toys? .a bike? Even worse (?), the place is open 24 hours a day. Good news for us foreigners; you can get your whole purchase tax-​free if it is over 5,000 yen. Mine turned out to be way more than that… just keep in mind that they wrap the whole thing up and you’re not supposed to open it until you leave Japan. Really! So be sure to take out the lychee & salt drink and green tea kitkats you meant to eat tonight, before letting them seal the bag. Great place to go if you are hungry, bored, forgot your phone charger in the previous hotel, or need to do last minute shopping. Just make sure you have enough money left in your card.

Don Quixote is a discount store located in the same building as the Richmond Hotel. They are open 24 hours a day and have almost anything you might want. Clothes because your airline lost yours? Second floor. Snacks, personal hygiene, cooking ingredients, health care items, wine, beer, toys, costumes, kitchen stuff, pet supplies, and hot, fresh meals. This place has it all.
Staff is friendly and service at the checkout is fast. To top it all of there is a huge aquarium out front with all kinds of cool salt water fish in it and their staircase plays music notes as you climb it!
Since this store is open 24 hours, I find myself coming here often when I can’t sleep or want snacks at odd hours. It’s really great.
