The stamps feature the 13 monsters from Toho's kaiju film franchise, including Godzilla himself. Itaindō will release the series as part of Godzilla's birthday on November 3, the 61st anniversary of the first film's premiere in Japan. The monstrous line-up includes Godzilla, Biollante, King Ghidorah, Mothra's caterpillar form, Mothra, Mecha-King Ghidorah, Baragon, SpaceGodzilla, Mecha-Godzilla, Battra caterpillar form, Battra, Gigan, and Rodan.

Stamps can be customized with individual names. The site isn't accepting pre-orders yet.

The company has also previously offered stamps featuring Free! Iwatobi Swim Club, Madoka Magica, Tiger & Bunny: The Rising, Uta-Pri, and more.
