Apple has launched a campaign that grants a 10% bonus when adding a balance to an Apple ID. Limited to December 12, 2019.
10% bonus for deposits of 100 to 30,000 yen for one person only
If you deposit your Apple ID by December 12, 2019 during the campaign period, 10% of the deposit will be given as a bonus once per person. Deposits subject to bonuses range from 100 yen to 30,000 yen.
However, depending on your account information and purchase history, you may not be able to use bonuses, such as having received a 10% bonus using a similar campaign in the past.
This Apple ID Deposit Bonus Campaign is the fourth implementation following the 5% bonus in March 2019, the 10% bonus in May 2019, and the 10% bonus in September 2019.
How to deposit to Apple ID
You can also make payments to your Apple ID from your iPhone / iPad / iPod touch on your iOS device, or from a Mac or Windows computer.
To deposit with an iOS device, launch the Apple Store, tap the person icon in the upper right, tap Deposit on Apple ID, and specify the amount to deposit.
You can use the balance deposited with your Apple ID to purchase music, movies, apps, books, iCloud storage, and more.
