Japanese Postage Stamps featuring Mount Fuji

A pair of mid-20th century Japanese postage stamps mounted in a philatelic collection. Both stamps feature a stylized depiction of Mount Fuji with an Imperial Chrysanthemum crest at the top. The stamp on the left is a 10 sen denomination in an orange-brown or terracotta hue, identified by the handwritten note below as the 1945-46 issue (Yvert 346). The stamp on the right is a 1 yen denomination in dark blue ink, identified as the 1946-47 issue (Yvert 355). These stamps reflect the transitional Showa era production, characterized by simplified, bold graphic design and utilitarian printing methods common during and immediately following World War II. The items appear to be printed on off-white or light grey paper and are mounted on a grid-patterned album page with typed Dutch-language text regarding volcanic activity. The blue 1 yen stamp shows visible cancellation marks, indicating it was postally used, while the 10 sen stamp appears cleaner but may also be used. Condition indicators show some slight tonal variations in the paper and minor alignment irregularities common to stamps of this period. The mounting uses black stamp hinges or mounts for protection.

I have examined the digital representation of two Japanese Showa-era stamps: a 1945 10-sen orange-brown and a 1946 1-yen blue, both featuring Mount Fuji and the Imperial Chrysanthemum. These stamps were produced during a period of extreme economic transition and material scarcity in post-WWII Japan. The 10-sen issue (Sakura #123) and the 1-yen issue (Sakura #127) are among the most common philatelic items of the era, issued in the hundreds of millions to meet basic postal needs during the inflation period. My visual assessment indicates the 1-yen specimen is postally used with a partial circular date stamp (CDS), while the 10-sen specimen appears to be either lightly used or a mint hinged copy. Condition is average for the period, showing typical centering issues and minor foxing consistent with the wood-pulp paper used at the time. The market for these specific issues is saturated; they are typically sold in bulk quantities or as inexpensive 'filler' stamps for beginner collections. High-value variants of these designs only exist in rare per-perforation errors or specific plate flourishes not visible here. As this is a digital examination, I cannot verify paper thickness, gum integrity, or the presence of hidden repairs. A physical inspection would be required to rule out sophisticated reprints, though the low market value makes forgery unlikely. For a definitive valuation, one would need to inspect the reverses for hinge damage or 'thinning' that would further decrease value. Currently, these stamps hold significantly more historical and educational value than financial equity.
