Finding the coupon exchange point isn't difficult! You don't need to exit the station; you can see it right at the North Exit. However, because the coupons are very new, each store is unaware of the promotion, so you have to ask everyone before you can use them! They don't give change or offer tax refunds, so it's not recommended if you're in a hurry, as the staff will ask you a lot of questions. The Uniqlo store is very small, with a limited selection of products. Initially, the staff insisted that only one coupon could be used at a time, but after communication and a long period of asking, we were finally able to use multiple coupons. The souvenirs I bought at Tokyo Station, combined with the Taiwan coupon and an additional 15% discount, were a really great deal.
