Notes:

• Rates assume standard envelope (≤25g, ≤119×235×5mm). Heavier/larger items cost more.
• Registered and EMS include ¥50,000 default insurance; additional coverage available.
• SAL (Surface Air Lifted) is discontinued for some destinations; verify at post office.
• Rates adjust annually (typically April 1). Check Japan Post Int'l Rate Calculator for real-time quotes.
