Second interest stack to my cute boy thing. Please also look at number one https://myanimelist.net/stacks/8358

Historical anime set in the Hein period + a few that feature Abe no Senmei.

The Heian era marked the height of Japan’s initial imperial aristocracy. With a strong focus on the arts, poetry, and literature; it cultivated the rise of samurai skilled in both aesthetics and battle. The Heian period essentially set the stage for the eventual shogunate and feudal period. Although seen as a rather peaceful era, it was actually rife with not all-out battles, but rather intrigue and power grabs behinds the scenes by the country’s most powerful and influential families; namely the Fujiwara, Genji (Minamoto), and Heike (Taira) clans.

This stack is dedicated to historical anime that have significant fantasy elements based on Japanese national folklore. A kind of fantasy chambara. The main criteria were a more or less realistic historical setting and significant elements of Japanese folklore (both natural and magical realism). But if you know of other shows that could be useful for this stack, then feel free to recommend them to me.

animes that are set in a Taisho (maybe shouwa) and earlier era, the stack is more for the aesthetic, that the kind of stories.
some series inspire in chine also made the cut
