I am always writing about U.S. stamp releases mainly because I and the majority of our members are in the U.S. Also, there are a lot of countries out there with a lot of stamps, like more than one by a whole bunch. We aren't a stamp collecting organization per se; so I don't try to announce every new release. (I like the Stamp Collecting Round-up blog for more world-wide news of stamps.)
However, Member Valerie sent over an article from Ping Magazine on all of last year's stamps from Japan. I very much enjoyed the article and thought you all might too. I especially liked the Letter Writing Day stamps (pictured). From the article: "Letter-Writing Day (Fumi no Hi) is a tradition originally founded by Japan Post back in 1979 to promote the fun of exchanging letters. It is celebrated on the 23rd day of every month and most of all on July 23rd. “Fumi” derives from the words for 2 (fu) and 3 (mi), while “Fumizuki” is an old name for July in Japanese. These two Kanji also mean “letter” and “month” — so it is literally THE perfect day to write a letter!" They also include a link to the Japan Post site about upcoming and past stamp issues.
