Historical/Traditional anime I actually like

• sparks of tomorrow (i guess not as accurate as i thought it would be but the writing is still one of the best)
• ōoku: the inner chambers (i love how it’s still historically accurate despite the plot)
• jaadugar: witch in mongolia
• love through a prism (ww1, not very big on the history part though, it comes late)
• mononoke anime and movie trilogy

Same as previous just haven’t watched, but it looks promising

• in this corner of the world
• heike monogatari
• from up on poppy hill
• croisée in a foreign labyrinth
