Foreign Mail Postmark Study Groups

Each of the Foreign Mail postmark study groups maintains a listing of all the different post offices where a usage of that postmark has been recorded, including the first and latest reported dates. Please refer to the current listings to determine if you can provide information about a new post office, or an amended first and/or last date for an existing entry.

Included are references of recent information published in Japanese Philately. Information about older references can be found in the Japanese Philately Cumulative Index.

Foreign Mail (Roman-Letter) Comb Postmarks used after World War II

When international mail resumed after World War II, a number of offices that had previously used Roman-letter cancellations temporarily resumed use of their comb cancellers.  These cancellers had either JAPAN or NIPPON in Part C.  As a matter of expediency, these “retro” comb postmarks were tolerated until a new foreign mail marking (the swordguard) was developed and approved by the occupying forces. Different post offices used cancellers with either metal or rubber components, and some of them used both. The OTARU cancel below is an example of a metal type that has large date numbers, while the TOKYO AMF cancel is and example of a rubber type with small date numbers.

Examples: Otaru  Tokyo

Foreign Mail (Roman-Letter) Comb Postmarks used for Administrative Purposes

After the comb cancellation was replaced with the swordguard in 1952, a modified version of the comb cancel continued to be used for administrative purposes.  In this modified comb the month appears in Roman numerals, whereas in the earlier combs the month appeared in Arabic numerals.
