If you are looking for some new gear in Assassin’s Creed Shadows, places like the Chasuriyama Kofun can be a good place to look. They come with a reward chest for the protagonist that completes it, making it a good idea to clear these when you find them. Additionally, even though the regions might have a higher level, you can go through the Kofun without any trouble as they are usually tests of your puzzle-solving abilities and not combat-related.
