Made of pure fragrant woods or filled with natural aromatic ingredients, this category of Japanese incense strives to come as close to all natural fragrance as possible. In some cases, the rare and fragrant wood base is highlighted as close to the actual wood as possible with little to nothing else added. For others in this category, pure natural 100% organics or natural floral essences are highlighted as the key notes. And for others, the focus is on ensuring nothing but 100% natural ingredients are used to ensure a pure fragrant experience.
