An official app has been created to enrich your Hills experience. Enjoy various benefits perfectly suited to you, including the delivery of personalized services and information as well as Premium Stage benefits based on your annual spending. You can also find special benefits and services that are only available to users of the HILLS APP. (Integrating the Hills With One ID) HILLS APP users will be asked to register a “Hills ID.” IDs that were previously issued per service will be combined into this “Hills ID” to integrate facilities and services throughout the city. This allows you to connect to each service smoothly and more seamlessly use the Hills’ services and information. (Using Your Smartphone as Your HILLS CARD) Upon registering as a Hills ID user, you will become a HILLS CARD member, and points earned on the HILLS APP can be used directly once at least 1 point are accrued. HILLS CARD Mastercard holders and certain Premium Stage members can also enjoy the exclusive benefit of using the parking fee service via a QR code. (Other Functions) • Search function (events, stores) Search and view event and store information for each of the “Hills” – Roppongi Hills, Toranomon Hills, ARK Hills, and Omotesando Hills. • My Benefits function Register your favorite benefits and use coupons. Make the most of your Hills life with the HILLS APP.
