Anime that are based within the Taisho time period. Majority are historical with a couple involving magic/ and or fantasy elements.

The Taisho era marks further Western influences in Japan from clothing to democracy. Still, the country makes a push in China, taking both island territories and areas into the North. There aren't a lot of anime set in the relatively short Taisho-era, but military motifs are almost always present.
