In about 1929, a suspended mailbox exclusively for air mail was introduced at the same time as the standard air mail mailbox. This suspended mailbox was made of wood. |
This suspended mailbox was made of sheet iron instead of cast iron. Two types were available, with the door over the opening for removing mail opened either vertically or sideways. The suspended mailbox shown in the photo above is the sideways opening type. |

From 1937, Japan was at war and research was conducted into the possibility of substitutes for the suspended as well as the standard mailboxes. Numerous wooden suspended mailboxes appeared at this time. |
In 1950, a decision was made to standardize the material and style of all suspended mailboxes throughout the country. Up to that time, each post bureau had set up its own suspended mailboxes. In 1968, the post bureau was renamed the Ministry of Posts and Telecommunications. |
