You can redeem your Osaka points by following these steps:

• Access the Osaka Rewards section from the left menu.
• Scroll down and find the redeem rewards section.

You will be able to see all the rewards you can get, but only those for which you have the necessary points will be unlocked.

Can I use my rewards and discounts all at once?

As for any other promo codes, keep in mind you can only use one at a time and must be applied before completing the payment of your next purchase.
