Postal Service

Easily identified by the "〒"symbol out front, post offices in Japan are ubiquitous. The Kyoto Central Post Office is located in front of Kyoto Station and is open for business 24 hours a day. The airmail rate for postcards is ¥70 to any overseas destination, an aerogramme costs ¥90. Letters weighing less than 10g cost ¥90 to other countries within Asia,¥110 to North America, Europe or Oceania, and ¥130 to Africa and South America. All post offices provide a reliable international Express Mail Service (EMS), which is as good as or better than private express shipping services.
Private Express Shipping Services
There are several options for international shipping, with the easiest by far being post offices operated by Japan Post. Their EMS (Express Mail Service) is speedy and reasonable. You can find more information at:
