While Staying in Japan Mail Post offices in Japan offer a wide range of services in addition to mail services, including savings accounts, insurance and pension accounts, remittances to foreign currency and postal money order services. For more general information on postal services, request a copy of the English-language Post Office Guide at a major post office. There are two types of mailboxes, both having two slots.
Hours are more restricted at local post offices, and for postal savings and insurance services.
If no letter is enclosed, a special reduced rate applies. To retrieve the material, you must bring the notice of delivery, some ID such as your alien registration card, and your inkan to the designated post office. Or fill in the notice listing an alternative delivery date and place and drop it in a mailbox. If you move within Japan, you can have your mail forwarded to your new address by filling in the appropriate postcard at your local post office. Any mail sent to your old address will be forwarded to your new address for one year.
