Here are some of the first pages from my Japan stamp collection.
Japan’s Showa series stamps are definitive postage stamps issued during the reign of Emperor Hirohito (the Showa period), spanning from 1937 through the early post-war era.
1st Showa Definitive Series (1937–1940)
Design Motifs: Classic imagery showcasing iconic cultural landmarks, historical figures, and scenic vistas.
Key Designs: Mount Fuji with cherry blossoms, General Nogi Maresuke, and the Horyu-ji temple pagoda.
Paper Types: Printed initially on distinct granite paper (containing tiny colored fibers) before transitioning to plain white paper.
Production: High-quality photogravure and engraving with standard, clean perforations.

2nd Showa Definitive Series (1942–1945)
Design Motifs: Heavily militaristic and industrial themes reflecting World War II mobilization.
Key Designs: War workers hammering, military pilots, fighter airplanes, and industrial factories alongside classic Mount Fuji with cherry blossoms imagery.
Austerity Measures: Production quality suffered heavily as the war progressed.
Perforations became rough or uneven, and the gum backing was often omitted due to resource shortages.

.
3rd Showa Definitive Series (1945–1946)
Design Motifs: Mostly repurposed wartime designs but produced under extreme emergency conditions immediately following Japan’s surrender.
Key Characteristics: These are completely imperforate (no holes, required cutting with scissors) and printed on coarse, poor-quality paper with no gum.
