This set of 20 regular 1-yen postage stamps from the 'New Nature of Japan' series stands out due to its Cartor imprint, particularly position 98, appealing to philatelists who appreciate nuanced production details.

Released in conjunction with Japan's efforts to promote its natural beauty, these stamps have become increasingly sought after, with collectors valuing complete rows for their aesthetic and historical significance.

The superb condition enhances its desirability, as stamps with even slight imperfections can diminish value in the collector market.

Given the catalog value of 320 yen, the current bid reflects a keen interest while remaining competitive within the Japan market.
