I don't have a great knowledge of Japanese artists so I'm still discovering the luminaries. I'm blown away by the work of Ayami Kojima, especially her paintings for the Caslevania franchise. I love her beautiful re-imagination of Western gothic tradition filtered though the (female) Japanese lens. Her male protagonists are, to our occidental eyes, etherial genderqueer beings - a fitting interpretation I feel of creatures that essentially a morbid evolution of the human.
No doubt they may have some insidious influence over my current vampiric miniatures project.
