How Does the Postal Service Work in Japan?

Japanese post offices are marked with a red postal symbol that looks like a T with a bar across the top.

Public mailboxes usually have two slots. The red slot is for domestic mail within Japan. The blue slot is for international mail and other mail services.

Regular airmail between Japan and the United States often takes about one week, though delivery times vary. The draft lists approximate international rates such as 70 yen for postcards and 90 to 130 yen for light letters or aerograms, depending on destination. Confirm current rates at the post office before mailing.

Japan Post also offers English-language phone support within Japan. Keep your Japanese address written clearly when sending or receiving packages.
