This article explains that when shipping to China, Japan, or South Korea, you must use the local language when entering the Address Line 1 and Address Line 2 fields.
Why this is required
This requirement comes from our shipping partners and is due to the limited number of Latin characters allowed in address line fields for these countries.
How to update the address
