[Important Notice] Enhanced Delivery Date & Time Validation for Japan Order CSV
Thank you for using “Japan Order CSV.”
We have implemented the following update to improve the usability of the app. This update enhances the delivery date and time validation functionality to help prevent delivery issues.
Details of the Update
1. Real-Time Validation on the Cart Page
When the cart is loaded, the app automatically checks whether the selected requested delivery date is a “past date” or earlier than the earliest available delivery date. If the selected date is invalid, an error message will be displayed, prompting the customer to make a correction.
＜Error Screen Example＞
2. Cutoff Time Restrictions for Same-Day Delivery
For same-day delivery time slots whose cutoff time has already passed at the time of checkout, the app settings have been updated to allow you to configure whether same-day delivery should still be available.
3. Final Validation on the Payment Page (Checkout)
Immediately before payment is completed, the app checks once again whether the selected delivery date is valid. If a past date has been selected, an error message will be displayed on the payment page, asking the customer to set their requested delivery date and time again.
＜Error Screen Example＞
4. Improved Synchronization for Shopify Plus-Only Features
We have optimized data synchronization from the cart to the checkout page. Consistent validation will now be performed both when the calendar is initially displayed and on the information entry and shipping method selection pages.
Update Schedule
The update was completed on the afternoon of March 4, 2026 (Wednesday).
You can also confirm the completion of the update on the support site's changelog.
※ The update is applied automatically, so you do not need to reinstall the app, although an app update message may appear.
Your current delivery date and time settings will remain unchanged.
After the update is complete, we recommend checking the “Delivery Date & Time Settings” in the app admin to ensure that they are configured as intended.
If you have any questions or need assistance with the settings, please feel free to contact our support team.
We sincerely appreciate your continued support of “Japan Order CSV.”
