Yes you can.
If you wish to cancel your Subscription, you must complete the “Cancel renewal” procedure before the next renewal date (based on Japan Standard Time ((GMT+9)).
The procedure is as follows.
Log into the store.
Click [Member Information].
Click [Member Information] in the menu.
Click [Purchase History].
Click the [Purchase History] button below the member information.
Click [Cancel renewal].
Select the Subscription you want to cancel and click [Cancel renewal].
Once “Cancel renewal” is set, the Subscription will be canceled on the next renewal date (based on Japan Standard Time ((GMT+9)). However the Subscription remains valid until then.
• Be aware that once you set “Cancel renewal,” the Subscription cannot be restored.
• Even after setting “Cancel renewal,” you must continue to pay the contract fee until the next contract renewal date.
