Postal mail in Japan
How to send a postcard in Japan
The mark of post office
When you want to send a postcard, write the address in your language and write clearly your country name in English and the words of "AIR MAIL" on it.
It takes about a week by air mail to receive the postcard.
But if you select "SEA MAIL", it takes more than a month.
The rate of sea mail is only slightly cheaper than air mail.
So you should write "AIR MAIL".
